5. Create a MATLAB script to find the first and second derivative of given function using Forward, Backward, central and Taylor numerical schemes. Test your code using the following functions: a. f(x)-xe +3x2 +21-Il and find f (3) and f'(3) for with h -0.1, 0.01 and 0.001 b. Approximate y'(1) and y'(1) using the following table f(x) 0.8 0.992 0.9 0.999 1.0 1.0 1.001 1.2 1.008 Input: (copy and paste the MATLAB or Scilab scrlpt in the following bos)
