Graph of f
The figure above shows the graph of f'(x), the derivative of the function f for
-3 < x < 5. The graph of f' has horizontal tangents at x = -1, x =2 and x = 4. The zeros of the derivative, f'(x), are x = -2, x= 2/3 and x =4.
(a) Find all value(s) of x on the interval (-3,5) at which f attains a relative minimum. Justify your answer.
(b) Find all value(s) of x on the interval (-3,5) at which f attains a relative maximum. Justify your answer.
(c) Find all value(s) of x on the interval (-3,5) at which the graph of f is concave up. Justify your answer.
