Question: 2. Approximate the second derivative of the function f(1) = (2 4.0) at x = 1 using the for- ward and the central difference approximations

2. Approximate the second derivative of the function f(1) = (2 4.0) at x = 1 using the for- ward and the central difference approximations with the following step sizes Ar = 1.6,0.4, 0.1. Compute also the exact value of the second derivative and the %errors of the approximations with respect to the exact value. Present the %errors for the different approximations and step sizes Ax in a table. Based on the table, conclude what approximation is the best one
