Chapter 4.4, Problem 17E

In Problems 15–22, use the given information to sketch the graph of f. Assume that f is continuous on its domain and that all intercepts are included in the table of values.

17.    Domain: All real x, except x = −2;

$\underset{x\to -2^{-}}{\lim }f\left(x\right)=\infty ;\underset{x\to \infty -2^{+}}{\lim }f\left(x\right)=-\infty ;\underset{x\to \infty }{\lim }f\left(x\right)=\text{}1$
