Consider the function f (x) = x³ - 2x + 4 on the interval [-2, 2] with h = 0.25. Use the forward, backward, andcentered finite difference approximations for the first andsecond derivatives so as to graphically illustrate which approximationis most accurate. Graph all three first-derivative finite difference approximations along with the theoretical, and do the same for the second derivative as well.
