Chapter 1: Q. 55 (page 88)

Sketch graphs by hand and use them to make approximations for each of the limits in Exercises 53–66. If a two-sided limit does not exist, describe the one-sided limits.
$\lim_{x \to 1} \frac{x^{2} - 1}{x - 1}$

Short Answer

Expert verified

The value is $\lim_{x \to 1} \frac{x^{2} - 1}{x - 1} = 2$ and graph is

Step by step solution

Step 1. Given information.
