Consider the following function and closed interval. Find g'(x). g'(x)= g(x) = (x²-1)2/3, [-4, 2] State any discontinuities of the function on the closed interval. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) x = Find all critical numbers of the function on the closed interval. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) x = Find the absolute extrema of the function on the closed interval. Use a graphing utility to verify your results. (Round your answers to two decimal places. If an answer does not exist, enter DNE.) absolute maximum (x, y) = absolute minimum (x, y) = smaller x-value (x, y) = larger x-value
