What happens to the expression 4x - 7 when it is multiplied by -1?
-4x - 7
4x + 7
4x - 7
-4x + 7
Multiplying by -1 changes the sign of each term in the expression. Thus, 4x becomes -4x and -7 becomes +7.
What is the result of expanding the expression 3(x + 2)?
3x + 6
3 + 2x
3x + 2
3x - 6
By applying the distributive property, you multiply 3 by both x and 2, yielding 3x + 6. This transformation demonstrates how distribution works in algebra.
After dividing every term of the equation 2x + 4 = 10 by 2, what is the resulting equation?
2x + 4 = 5
x + 4 = 10
x + 2 = 5
2x + 2 = 5
Dividing each term of the equation by 2 simplifies it to x + 2 = 5. This balanced transformation makes solving for x more straightforward.
To solve the equation x + 3 = 8, which transformation is needed to isolate the variable?
Multiply both sides by 3
Subtract 3 from both sides
Add 3 to both sides
Divide both sides by 3
Subtracting 3 from both sides eliminates the constant on the left side, isolating x. This balanced operation is the essential step needed to solve the equation.
What is the simplified form of the expression 2x + 3x - 4 after combining like terms?
x - 4
6x - 4
5x + 4
5x - 4
Combining the like terms 2x and 3x results in 5x, and the constant remains -4. This basic transformation reinforces the process of collecting similar terms.
Simplify the expression: 2(x - 3) + 4(x + 5).
6x + 14
8x + 8
8x + 14
6x + 8
First, distribute to obtain 2x - 6 and 4x + 20. Then, combine like terms: 2x + 4x equals 6x and -6 + 20 equals 14, resulting in 6x + 14.
Which transformation correctly factors the quadratic expression x² + 5x + 6?
(x + 3)(x + 3)
(x + 1)(x + 6)
x(x + 5) + 6
(x + 2)(x + 3)
The quadratic x² + 5x + 6 factors into two binomials where the factors of 6 add up to 5, which are 2 and 3. Hence, (x + 2)(x + 3) is the correct factorization.
Solve the equation 3x - 4 = 2x + 1 by transforming it into a simpler form.
x = 3
x = 5
x = 1
x = -5
Subtract 2x from both sides to obtain x - 4 = 1, and then add 4 to isolate x, resulting in x = 5. This sequential transformation makes the problem easier to solve.
Rewrite the expression 2x² - 8 in its fully factored form.
2(x² - 4)
2x(x - 4)
(2x - 4)(x + 2)
2(x - 2)(x + 2)
First, factor out the common factor 2 to get 2(x² - 4), then recognize x² - 4 as a difference of squares which factors into (x - 2)(x + 2). This yields the fully factored form 2(x - 2)(x + 2).
Simplify the expression 5(x + 2) - 3(x - 4).
8x - 2
8x + 6
2x + 22
2x - 2
By distributing, 5(x + 2) becomes 5x + 10 and -3(x - 4) becomes -3x + 12. Combining like terms gives (5x - 3x) + (10 + 12) which simplifies to 2x + 22.
Transform the expression x² + 6x + 5 by completing the square.
(x + 3)² + 4
(x + 3)²
x² + 6x
(x + 3)² - 4
Completing the square involves rewriting x² + 6x as (x + 3)² - 9, then adding the constant 5 to result in (x + 3)² - 4. This method transforms the quadratic into a perfect square minus a number.
Solve the equation 4(x - 2) = 2x + 10 by applying the appropriate transformations.
x = 8
x = -9
x = 10
x = 9
Expanding the left side gives 4x - 8, and setting 4x - 8 equal to 2x + 10 allows you to subtract 2x from both sides, resulting in 2x - 8 = 10. Adding 8 then gives 2x = 18, so x equals 9.
What is the result of applying the distributive property to the expression -3(2x - 7)?
6x - 21
6x + 21
-6x + 21
-6x - 21
Multiplying -3 by 2x yields -6x, and -3 by -7 gives +21. The distributive property transforms the expression into -6x + 21.
Choose the correctly transformed equivalent expression for 4 - (x - 5).
9 - x
x - 9
9 + x
4 - x - 5
Distribute the negative sign inside the parentheses to get 4 - x + 5, which simplifies by combining the constants to 9 - x. This shows proper handling of subtraction over a group.
Find the value of y that satisfies the equation 3(2y - 4) = 18.
y = 6
y = 5
y = 4
y = 3
Distribute 3 to obtain 6y - 12, then set 6y - 12 equal to 18. Adding 12 to both sides gives 6y = 30, and dividing by 6 results in y = 5.
Solve for x: (x + 1)/2 - (x - 3)/3 = 1/6.
x = -8
x = -2
x = 8
x = 2
Multiplying the entire equation by 6 eliminates the fractions, leading to 3(x + 1) - 2(x - 3) = 1. Simplifying this equation results in x + 9 = 1, and solving for x gives x = -8.
Which transformation correctly simplifies the rational expression (3x² - 12)/3?
x² - 12
x² - 4
3x² - 4
3x - 4
Dividing each term in the numerator by 3 simplifies the expression to x² - 4. This transformation effectively reduces the expression by the common factor.
Transform the expression 2(x - 3) - 3(2 - x) into its simplest form.
x + 12
5x + 12
x - 12
5x - 12
Expanding both terms gives 2x - 6 and -6 + 3x, respectively. When combined, the x terms yield 5x and the constants combine to -12, resulting in 5x - 12.
Factor the expression 9 - 16x² completely.
9 - 4x²
(3 - 4x)(3 + 4x)
(3 - 4x)²
(3 + 4x)²
Recognize that 9 is 3² and 16x² is (4x)². The expression represents a difference of squares and factors into (3 - 4x)(3 + 4x).
Apply a sequence of transformations to simplify the expression 2x - [3 - 2(1 - x)].
2x + 1
1
-1
2x - 1
Begin by simplifying inside the brackets: 2(1 - x) becomes 2 - 2x, so the bracket expression is 3 - (2 - 2x) which simplifies to 1 + 2x. Subtracting this from 2x ultimately gives -1.

Transformation Test Answers & Review Cheat Sheet

  1. Types of Transformations - Understanding the four main transformation families helps you predict exactly how graphs shift, flip, and stretch. With translation, reflection, rotation, and scaling in your toolkit, you can reshape any function like a pro. Ready to explore each type one by one? Transformations of Functions
    2. Transformations of Functions
  2. Vertical Translations - Add or subtract a constant outside the function to slide it up or down the y-axis. For example, f(x) + k lifts your graph by k units, while f(x) - k drops it by k units. It's like giving your graph its own personal elevator! Translations
    3. Translations
  3. Horizontal Translations - Insert a constant inside the function argument to glide it left or right. So f(x - h) shifts right by h units, and f(x + h) scoots left by h units. Picture your graph cruising along the x-axis like a smooth highway ride! Translations
    4. Translations
  4. Vertical Reflections - Multiply the function by - 1 to flip it over the x‑axis. This turns f(x) into - f(x), mirroring all peaks and valleys upside down. Think of it as seeing your graph's reflection in a still pond! Reflections
    5. Reflections
  5. Horizontal Reflections - Swap x for - x inside the function to flip the graph over the y‑axis, changing f(x) into f( - x). Left becomes right and right becomes left! Imagine folding your graph along the vertical line and watching it mirror itself. Reflections
    6. Reflections
  6. Vertical Stretching and Compressing - Multiply the function by a constant a to make it taller or shorter. If a > 1, the graph stretches away from the x‑axis; if 0 < a < 1, it compresses closer. It's like tuning the tightness of a rubber band under tension! Stretching and Shrinking
    7. Stretching and Shrinking
  7. Horizontal Stretching and Compressing - Tweak the input by multiplying x by b inside the function. When b > 1, the graph compresses toward the y‑axis; when 0 < b < 1, it stretches outward horizontally. Imagine your graph taking a deep stretch or a cozy squeeze sideways! Stretching and Shrinking
    8. Stretching and Shrinking
  8. Combining Transformations - Mix translations, reflections, and scalings to supercharge your graphs. Apply transformations one at a time to see how they stack up and interact. This step-by-step approach builds real mastery over complex graph shifts! Transformations Practice Problems
    9. Transformations Practice Problems
  9. Transformations on Different Functions - Test linear, quadratic, absolute value, and more to see how each shape reacts. You'll notice patterns and surprises when the same transformation hits different curves. Practice across various graphs to cement your understanding! Graph Transformations Practice Questions
    10. Graph Transformations Practice Questions
  10. Reinforce with Practice Problems - Challenge yourself with targeted exercises to lock in your skills. Working through problems helps turn fresh concepts into second nature. Before you know it, you'll be bending, flipping, and shifting graphs like a true function ninja! Transformations Practice Problems
