Consider the following function. f(x) = 16 - x^(2/3) Find f(-64) and f(64). Find all values c in (-64, 64) such that f'(c) = 0. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) Based off of this information, what conclusions can be made about Rolle's Theorem? This contradicts Rolle's Theorem, since f is differentiable, f(-64) = f(64), and f'(c) = 0 exists, but c is not in (-64, 64). This does not contradict Rolle's Theorem, since f(0) = 0, and 0 is in the interval (-64, 64). This contradicts Rolle's Theorem, since f(-64) = f(64), there should exist a number c in (-64, 64) such that f'(c) = 0. This does not contradict Rolle's Theorem, since f'(0) does not exist, and so f is not differentiable on (-64, 64). Nothing can be concluded.

If it does not satisfy the hypotheses, enter DNE).
