Please show how to initiate this problem on pencil and paper to find the values of A,B,C,D and E and then show how to code this in MATLAB. Thank you!

Consider the following approximation: f()Af(x 2h)+B f( h)Cf()Df(x +h) E f(z +2h). 1) Determine the values of the constants A, B, C, D, and E so that the ap- proximation is as accurate as possible. What is the order of the error? Please note this is (at least somewhat) a "pencil and paper" exercise
