Graph all three first-dervative finite difference

Reference no: EM13620731

Consider the function f(x)=x^3-2x+4 on the interval [-2,2] with h=0.25. Use the forward, backward, and centered finite difference approximations for the first and second derivatives so as to graphically illustrate which approximation is most accurate. Graph all three first-dervative finite difference approximations along with the theoretical, and do the same for the second derivative as well.
