Question 1023646: Sketch the graph of the function:
y=(x-2)(x-3(x+5)
1- Determine the end behavior of the function.
2- Find all x-intercepts:

-2
-1
0
1
2

3- Find all y-intercepts.
60
48
30
12
0
4- Use the x-intercepts to divide the x axis into intervals

5- Choose at least one point within each interval to show whether the function is positive or negative.
6- Sketch the graph.
I have the partial answer but I am having difficulty with the rest. Help would be greatly appreciated.
