Find the absolute maximum value on (0, 00) for f(x) = x4 - 4x3. (E Select the correct choice below and, if necessary, ll in the answer boxes to complete your choice. (:3. A. The absolute maximum is at x = B. There is no absolute maximum. Describe the graph of f at the given point relative to the existence of a local maximum or minimum. Assume that f(x) is continuous on (- oo, oo). (6,f(6)) if f'(6) = o and f\"(6)
