These 2 questions please and all calculations must be done inmatlab. I need the matlab codes please21.19 The objective of this problem is to compare second- order accurate forward, backward, and centered finite- difference approximations of the first derivative of a function to the actual value of the derivative. This will be done for f (x) = e-2x-X (a) Use calculus to determine the correct value of the deriv- ative at x 2. (b) Develop an M-file function to
