Please solve ..Thank you

Question 1: Maximize the function f(x) = (45*x + 70) / (x2 - 16*x + 125) using the the variable step size gradient algorithm. Use Ax = 0.0001 when calculating the numerical derivative. Take the initial step size as ss = 8 and start with x, = 20. Apply 5 iterations of the algorithm and report x, f(x) and f'(x) values with three decimal digits. You should report X1, X2, X3, X4, Xs, X6 and similarly with f(x) and f(x)
