Question 950577: How would I go about finding the graph of this polynomial? would I need a table of signs in order to fully graph?
+H%28x%29+=+x%5E3+-+5x%5E2+-+24x+
Thank you!

You can put this solution on YOUR website!
You can factor,
H%28x%29=x%28x%5E2-5x-24%29
H%28x%29=x%28x%2B3%29%28x-8%29
So now you know that the zeros are x=0, x=-3, and x=8.
You can choose points in between to get values.
