Use the graph of fx to identify x-values where fx has a

Question

For each function in Problem do the following.

(a) Find f'(x).

(b) Graph both f(x) and f'(x) with a graphing utility.

(c) Use the graph of f'(x) to identify x-values where f(x) = 0, f(x) >, and f(x) < 0.

(d) Use the graph of f(x) to identify x-values where f(x) has a maximum or minimum point, where the graph of f(x) is rising, and where the graph of f(x) is falling.

f(x) = x³ - 12x - 5
