Can someone please explain how to solve for this using MatLab

2. Exercise Let's differentiate the following function: f(x) e -2x+1 f'(x) = ??? What is the first derivative of this function at x- 1? Now, numerically evaluate the approximate first derivative of this function at x = 1 by: (a) Forward finite difference method, using an interval of h = 0.1 (b) Backward finite difference method, using an interval of h = 0.1 (c) Centered finite difference method, using an interval of h = 0.1 Calculate the error of each method by comparing the numerical derivative with the result from calculus method (above
