Given the graph of the polynomial function y=f(x), determine the following

A. The intervals of increase/decrease
B.the end behaviors
C. The number of critical points

It seems I do not have access to the graph of the polynomial function y=f(x) that you are referring to. In order to determine the intervals of increase/decrease, the end behaviors, and the number of critical points, I would need to see the graph of the function. Could you please provide a description or details of the graph so that I can help you with your question?
