can anyone help me solve this in python 2.7 version please. Don't need the graphical help, just need the data.

Consider the function f(x) = x3 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-derivative finite difference approximations along with the theoretical, and do the same for the second derivative as well.
