Extracted text: The function f graphed below is defined by a polynomial expression of degree 4. Use the graph to solve the exercise. y A To find a function value f(a) from the graph of f, we find the height of the graph above the x-axis at x = From the graph of f, we see that f(3) = and f(2) = The net change in f between x = 2 and x = 3 is
