10-146.

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

1. $y = \left(x + 1\right)^{2}\left(x − 2\right)^{2}\left(x − 5\right)^{2}$

What are the roots?

Look closely at the equation and graph, what are the x-intercepts?

Double roots at $−1, 2, 5$.

2. $y = −\left(x + 1\right)^{2}\left(x − 2\right)^{2}\left(x − 5\right)^{2}$
