Make a sketch of the graph of each of the following functions. Describe the graphs. Homework Help ✎
y = (x + 1)2(x − 2)2(x − 5)2
y = −(x + 1)2(x − 2)2(x − 5)2
Identify the y-intercept and all of the x-intercepts.
What is the degree of the polynomial?
How does this relate to the end behavior of the graph?
Any factor that is 'squared' creates a double root.
What do double roots look like on a graph?
This graph is almost the same as the graph in part (a).
How is it different?
