9-93.

Make a sketch of the graph of each of the following functions. Describe the graphs.

$y = (x + 1)^2(x - 2)^2(x - 5)^2$
Hint 1(a):
Identify the $y$ -intercept and all of the $x$ -intercepts.
Hint 2(a):
What is the degree of the polynomial?
How does this relate to the end behavior of the graph?
More Help (a):
Any factor that is 'squared' creates a double root.
What do double roots look like on a graph?

$y = -(x + 1)^2(x - 2)^2(x - 5)^2$
Hint (b):
This graph is almost the same as the graph in part (a).
How is it different?
