You may assume that f'fx) is continuous, f'(x) is defined for all x, and f'(x) : 0 only when x : 4, x = 0, and x = 8. O {(x) has three critical points, one relative maximum, and one relative minimum. 0 f(x) has two critical points and no relative extrema. 0 f(x) has three critical points, two relative maximums, and one relative minimum. 0 {(x) has two critical points, one relative maximum, and one relative minimum. 0 f(x) has three critical points, one relative maximum, and two relative minimums
