Tell you what. I'll do the graph, and you answer the questions.
http://www.wolframalpha.com/input/?i=-x(x-1)(x%2B2)
refer to the polynomial function f(x)= -x(x-1)(x+2) in anwering the folloowing questions.
1.what is the y intercept?
2.what is the behavior of the left end of its graph?
3.will the graph pass through the origin?
4,what is the behavior of the left end of this graph?
5how many turning points does the graph will have?
6.what is the degree.
7.is there a point where the graph is tangent to the x axis?
