5-67.

Let .

Identify all of the roots of the function.

All of the rational roots will be factors of

. You can graph the function to help see the rational roots.

Recall that if, thenis a factor that can be divided out of the polynomial. Use the roots to sketch a prediction of what you think the graph of

will look like.Use a graphing calculator to check your prediction.
