Tommy has a rectangular-shaped swimming pool. He wants to know the volume of water in the pool, but he is not sure what the width of the pool is. He knows the relationship between the width and the length and height of the pool. He used this relationship to come up with the following equation to find the volume of the pool when the width is w meters. V(w)=w^3+6w^2-16w Using the end behavior of V(w), determine the graph of the function.
