Example 1: Jeannie wishes to construct a cylinder closed at both ends. The figure below shows the graph of a cubic polynomial function used to model the volume of the cylinder as a function of the radius if the cylinder is constructed using 150π cm 2 of material. Use the graph to answer the questions below.

The constant coefficient is the negative product of the roots for a cubic. In general, this coefficient is either the positive or negative of the product of the roots for any polynomial. The sign depends on the degree of the polynomial – if it's even, the sum is the positive one, otherwise it's negative.
