Evaluate each limit. If the limit does not exist due to a vertical asymptote, then add an approach statement stating if is approaching negative or positive infinity. Homework Help ✎

As with all limits where

or,compare the highest-power term in the numerator with the highest-power term in the denominator. Be sure to consider coefficients.

This is Ana's method to find a derivative. If you need more guidance, refer to the hints in problem 3-110 part (b).

Or you could multiply the numerator and the denominator by the conjugate of

.

When you evaluate at

, there is ain the denominator. Perhaps you can cancel it out. Try factoring.

Refer to the hint in part (a).
