Chapter 4.4, Problem 18E

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.

18.    Domain: All real x, except x = 1;

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

x	−4	−2	0	2
f(x)	0	−2	0	0
