Solve using MATLAB and provide code please 4. The first derivative of a function f(x) at a point x = xo can be approximated with the four-point central difference formula: dx 12h where h is a small number relative to xo. Write a user-defined function function that calculates the derivative of a math function fx) by using the four-point central difference formula. For the user-defined function name, use dfax-FoPrder(Fun, x0), where Fun is a name for the function that is...
