centered difference approximation

centered difference approximation

Use a centered difference approximation of O(h2) to estimate the second derivative of the function Perform the evaluation at x = 2 using step sizes of h = 0.25 and 0.125. Compare your estimates with the true value of the second derivative. Interpret your results on the basis of the remainder term of the Taylor series expansion.
Problem:
f (x) = 25×3− 6×2+ 7x –88
