When you write a polynomial in the form
You know that you have a polynomial of degree , which crosses the x axis at
So, in your case, you have a cubic which crosses the x axis at x=-5, x=-1 and x=2.
Moreover, since A=1/2 is positive, the end behaviour of the cubic is preserved, i.e.
This is all the information you need to sketch a first draft of the graph.
