What is the value of lim??2 (x² + 3x - 2)?
8

10
Polynomials are continuous everywhere, so you can find the limit by direct substitution: 2² + 3·2 - 2 = 4 + 6 - 2 = 8. For more on limits of polynomials, see Mathsisfun.
Evaluate lim??3 5.

0
Undefined
3
The limit of a constant function is the constant itself, regardless of the approach value. This is a basic property of limits. More details at Lamar University Calculus.
Compute lim??0 (sin x)/x.

?
sin?0
The classic limit lim??0 sin?x/x = 1 can be proven using the squeeze theorem or power series expansion. It’s fundamental in calculus. For a proof, see ProofWiki.
Find lim??? (3x² + 1)/(x² - x).

?
Divide numerator and denominator by x²: (3 + 1/x²)/(1 - 1/x) ? 3/1 = 3 as x??. This uses end?behavior analysis for rational functions. More at Khan Academy.
Evaluate lim??0 (1 - cos x)/x².
1/2

2
Using the Taylor series expansion cos?x ? 1 - x²/2 + … shows (1 - cos?x)/x² ? 1/2. Alternatively, apply l'Hôpital’s rule twice. See L'Hôpital’s Rule for details.
What is lim??1 (x³ - 1)/(x - 1)?
3
0
1
2
Factor x³ - 1 = (x - 1)(x² + x + 1), then cancel (x - 1) and substitute x=1 into x² + x + 1 to get 3. Factoring techniques are key. More at Mathsisfun.
Find lim??0 (e^(2x) - 1)/x.
2
1
0
e²
Use the derivative of e^(2x) at 0 or l'Hôpital’s rule: the derivative of e^(2x) at x=0 times 1 yields 2. Thus the limit is 2. More at Khan Academy.
Determine lim??0 |x|/x.
-1
0
1
Does not exist
The one?sided limits differ: from the right |x|/x = 1, from the left |x|/x = -1, so the two?sided limit does not exist. This shows the importance of checking one?sided behavior. See Wikipedia on One?Sided Limits.

Study Outcomes

  1. Understand key concepts behind limit calculus questions -

    Grasp fundamental definitions and properties of limits to determine the behavior of functions as they approach specific points or infinity.

  2. Analyze limits from graphical data -

    Examine and interpret graphs to determine limits, one-sided limits, and identify discontinuities as featured in this calculus limits quiz.

  3. Apply algebraic methods in the limits test -

    Use techniques such as factoring, rationalization, and common denominators to evaluate challenging limits accurately.

  4. Employ L'Hôpital's Rule for indeterminate forms -

    Recognize 0/0 and ∞/∞ cases and apply L'Hôpital's Rule to resolve indeterminate limits with confidence.

  5. Interpret one-sided limits and continuity -

    Determine left- and right-hand limits to assess function continuity and classify different types of discontinuities.

  6. Solve real-world scenarios using limits -

    Translate applied problems into limit expressions and solve them to model phenomena such as instantaneous rates of change.

Cheat Sheet

  1. Fundamental Definition of a Limit -

    According to MIT OpenCourseWare, when tackling limit calculus questions, limx→a f(x)=L means f(x) gets arbitrarily close to L as x approaches a. Practice rewriting functions to test the ε - δ definition or use the mnemonic "Epsilon - Delta Dance" to remember how neighborhoods shrink around a point.

  2. Algebraic Techniques for Evaluating Limits -

    In any calculus limits quiz or limits test, direct substitution is your first stop, but if you hit 0/0, factor and cancel or rationalize using conjugates (for roots) to simplify expressions. When standard methods fail, L'Hôpital's Rule, lim f❄g=lim f′❄g′ for indeterminate forms, is your go-to tool as endorsed by Khan Academy courses.

  3. One-Sided Limits and Continuity Checks -

    Harvard's calculus materials highlight that limx→a❻ f(x) and limx→a❺ f(x) must agree for a two-sided limit to exist; a mismatch signals a jump discontinuity. Remember: continuity at a demands lim f(x)=f(a), which you can test quickly in a limits test by plugging in values slightly less and greater than a.

  4. Limits at Infinity and Horizontal Asymptotes -

    As seen in Stanford's online lectures, for rational functions, the limit as x→±∞ depends on leading terms: equal degrees give the horizontal asymptote as the ratio of leading coefficients, smaller numerator degrees yield zero, and larger yield ±∞. A simple mnemonic is "Big over Small means Zero; Equal means Ratio; Top over Bottom means Infinity."

  5. Graphical Interpretation for Limit Problems -

    According to Wolfram MathWorld, analyzing a graph for holes, jumps, and asymptotes is crucial in a limits quiz; identify where f(x) approaches a value versus where f(a) is defined. Use the "Eye-Sight Check" trick: imagine zooming in infinitely on the graph near x=a to see if the curve straightens to a single y-value.
