8-126.

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

*f*(–1)?Evaluate

. Hint: Use polynomial division. Use what your answer to part (b) to sketch

*y*=*f*(*x*) without using a calculator.If

*y*=*f*(*x*) continuous at*x*= –1? Use the definition of continuity to justify your answer.

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.
