Consider the function f(x) = x3 - 2x - 4x + 8 on the interval [-1, 3]. Find f'(x). f'(x) = 3x-4x-4 Find the critical values. X = Evaluate the function at the critical values. (x, y) = (x, y) = (smaller x-value) (larger x-value) Evaluate the function at the endpoints of the given interval. (x, y) = (smaller x-value) (larger x-value) (x, y) = Find the absolute maxima and minima for f(x) on the interval [-1, 3]. absolute maximum (x, y) = absolute minimum (x, y) = =
