Properties of Graphs of Polynomial Functions Terminology Associated with Graphs of Polynomial Functions Detennine what types of polynomial functions/, g, and hare graphed below Give a reason for your conclusions based on the zeros of each function + j _, r -6- - g(x) + 5 + ;;, As we begin to study the graphs of polynomial functions, there are other properties of graphs that now can be identified For the remainder of this lesson, we will define terms and then we will identify these tenns on from the graphs of the given functions
