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) > 0, 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) = 8 - 2x - x2
