For this exercise, use a graphing utility to estimate the local extrema of the function and determine the intervals on which the function is increasing and decreasing. The function is given by f(x) = x^4 - 8x^3 + 1. Which of the following options correctly describes the graph of the function?
A. The function has a local maximum at x = -2 and a local minimum at x = 2.
B. The function has a local maximum at x = 2 and a local minimum at x = -2.
C. The function has a local maximum at x = -2 and no local minimum.
D. The function has a local maximum at x = 2 and no local minimum.
