The function f graphed below is defined by a polynomial expression of degree 4. Use the graph to solve the exercise. -3 (a) A function value f(a) is a local maximum value of fif f(a) is the ---Select--- | value of f on some open interval containing a. From the graph of f we see that there are two local maximum values of f: one local maximum is and it occurs when x = 2; the other local maximum is and it occurs when X (b) The function value f(a) is a local minimum value of fif f(a) is the ---Select--- |value of f on some open interval containing a. From the graph of f we see that there is one local minimum value of f. The local minimum value is and it occurs when x =
