8-107.

Make rough sketches of the graphs of each of the following polynomial functions. Be sure to label the $x$- and $y$- intercepts.

1. $y = x(2x + 5)(2x - 7)$

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

1. $y = (15 - 2x)^2(x + 3)$
This is a cubic function, but there are only two $x$-intercepts because on one of the factors is squared. This factor creates a double root.
