Find an example of a function such that the limit exists at every x, but that has an in nite number of discontinuities. (You can describe the function and/or write a
Notice that the limits on this worksheet can be evaluated using direct substitution, but the purpose of the problems here is to give you practice at using the Limit Laws. Evaluate this limit using the Limit Laws. Show each step. lim (2 2 − 3 + 4) 5.

Worksheet by Kuta Software LLC. Kuta Software - Infinite Calculus. Evaluating Limits. Evaluate each limit. 1) lim 5. x→−1. 5. 3) lim ( x3 − x2 − 4) x→2. 0. 5) lim − x + 3. x→3. − 6. x − 4. 7) lim −. x→1. x2 − 6 x + 8. 1. 9) lim sin ( x) x→ π. 0. Critical thinking questions: 11) Give an example of a limit that evaluates to 4. Many answers.
Limits are a very powerful tool in mathematics and are used throughout calculus and beyond. The key idea is that a limit is what I like to call a \behavior operator". A limit will tell you the behavior of a function nearby a point.
Worksheet # 4: Basic Limit Laws 1. Given lim x!2 f(x) = 5 and lim x!2 g(x) = 2, use limit laws (justify your work) to compute the follow-ing limits. Note when working through a limit problem that your answers should be a chain of equalities. Make sure to keep the lim x!a operator until the very last step. (a) lim x!2 2f(x) g(x) (b) lim x!2 f(x ...
The table above gives selected values and limits of the functions 𝑓𝑓, 𝑔𝑔, and ℎ. What is lim 𝑥𝑥→5 ℎ(𝑥𝑥) 𝑓𝑓(𝑥𝑥) + 2𝑔𝑔(𝑥𝑥) −ℎ(5) ? Example 4: Piecewise Functions . Piecewise defined functions and limits 𝑓𝑓(𝑥𝑥) = √11 −𝑥𝑥
