Answer
a) $\lim\limits_{x \to -\infty}f(x) = 0$
b) $\lim\limits_{x \to +\infty}f(x) = -1$
Work Step by Step
a) We see that as x decreases, the function gets closer and closer to 0 from above but does not reach it. We therefore assume that as x grows infinitely small, the function trends towards 0
b) We see that as x increases, the function starts to grow closer and closer to -1 from below but does not reach it. We therefore assume that as x grows infinitely large, the function trends towards -1
