9-8.

For each equation below, make tables that include

*x*-values from −2 to 2 and draw each graph. Homework Help ✎*y*= (*x*− 1)^{2}(*x*+ 1)*y*= (*x*− 1)^{2}(*x*+ 1)^{2}*y*=*x*^{3}− 4*x*What are the parent functions for these equations?

Use the same method as in parts (a) and (b).

What is the highest-valued exponent?

The parent function is *y* = *x*^{3}.*y* = (*x* − 1)^{2}(*x* + 1)*y* = (*x*^{2} − 2*x* + 1)(*x* + 1)*y* = *x*^{3} − *x*^{2} − *x* + 1
