For what values of the numbers a and b does the function f(x) = axe ba 2 have a maximum value f(7) = 2? a = OVSuppose f" (x) is continuous on (-0o, 0o) If f'(4) = 0 and f"(4) = -7, what does that tell you about f? O f is increasing at x = 4 O f is decreasing at x = 4 O f has a local maximum at x = 4 O f has a local minimum at x = 4 Nothing can be said about f
