Answer
a. See the table, $2.000$
b. See the graph, $2.0$
c. $2$
Work Step by Step
a. From the table, $\lim\limits_{x \to -1}\frac{x^2-1}{|x|-1}\approx 2.000$
b. From the graph, $\lim\limits_{x \to -1}\frac{x^2-1}{|x|-1}\approx 2.0$
c. $\lim\limits_{x \to -1}\frac{x^2-1}{|x|-1}=\lim\limits_{x \to -1}\frac{(x+1)(x-1)}{-x-1}=\lim\limits_{x \to -1}(-x+1)=2$
