AVAV The graph of a function f(x) and the graph of its derivative, f'(x), are shown to the left. Which is which? Hint: When f(x) increases > f '(x) is positive. When f(x) decreases->f'(x) is negative. O is purple; /' is orange is orange; is purple -10 / -8 Challenge #7: Sketch the derivative of the function, h(x).
