I just need help with the MATLAB code (part (B))!!!

1. In this problem, we use thae-h)to approximate f(ro), ie. f(ro) etb(Hint: subtract the Taylor expansion of f(o h) from the Taylor expansion of f(xo -h) (A). Show, using the Taylor expansions of both f(xo h) and f(xo - h), that the leading term of the error is l'Ymlh2 (B). Write a Matlab program to compute the actual errors for f(x) = e2x, xo = 1.2, and h = 10-,- 1,...,20, and the approximation given by this problem. Draw the graphs of the actual errors and the leading term of error
