[4pts] Problem #5) a) Write a MATLAB function "ScndDeriv.m" that takes the second derivative of function f() using the forward difference method or the central difference method The MATLAB function takes in the function f(x), the derivative location x, the size of Ar, and the option of selecting one of the two methods, and outputs the second derivative value. b) Using the MATLAB function from part a), take the second derivative for the following functions at x -2 f (x) = ex^-3 + 2x Forward difference method and Ar 1 Forward difference method and Ar-0. Forward difference method and -0.01 f(x) = sin (x) + 4e0 3x + 7 Central difference method and Central difference method and -0.05 Central difference method and Ar = 0.001
