Answer
b
Work Step by Step
Since the limit approaching 1 from the left $\lim\limits_{x \to 1^{-}}$ equals -$\infty$
and the limit approaching 1 from the right $\lim\limits_{x \to 1^{-}}$ also equals -$\infty$,
then the limit approaching 1 from both sides has to equal -$\infty$
$\lim\limits_{x \to 1^{}}$ = -$\infty$
