8-107.

Make rough sketches of the graphs of each of the following polynomial functions. Be sure to label the

*x*- and*y*- intercepts. Homework Help ✎*y*=*x*(2*x*+ 5)(2*x*− 7)*y*= (15 − 2*x*)^{2}(*x*+ 3)

Determine the *x*-intercepts using the Zero Product Property.

Use your graphing calculator to check your graph.

This is a cubic function, but there are only two *x*-intercepts because on of the factors in squared. This factor creates a double root.
