   3. There are three factors containing x; therefore, the expanded form of the polynomial is of degree 3. The degree of the polynomial is odd and the polynomial has a positive leading coefficient. The graph will start in quadrant 3 and end in quadrant 1. Substituting zero for x gives the y-intercept (0, 16).
