Chapter 3 - The Derivative - 3.1 Limits - 3.1 Exercises: 4

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 -$\infty$ $\lim\limits_{x \to 1^{}}$ = -$\infty$
