8-72.

Given

*f*(*x*) =. Homework Help ✎ What is the value of

*f*(−1)?Find

. (Hint: polynomial division) Use what you found from part (b) to sketch

*f*(*x*) without using a calculator.

What happens when the denominator is 0?

Substitute *x* = −1 into the quotient.

You know it is a parabola with a hole at *x* = −1. Find the *x*-intercepts by factoring.
