You are having a conference call with the CEO of a paper company. You have interpreted the number of trees cut down versus profit as the function P(x) =-*4 + x3 +7x2 - x - 6. Describe to the CEO what the graph looks like and, in general, how to sketch the graph without using technology. Use complete sentences, and focus on the end behaviors of the graph and where the company will break even (where P(x) = 0).
