Please use Visual Basic Thank you

1. Write a Visual Basic program to find the optimum value xopt that maximizes the value of a function f(x) using the Golden Search method. The inputs for the program are the lower value xi, the upper value xu and the allowable error as a percentage. The program should run a maximum of 100 iterations, and should report an error if convergence does not happen. The output for the program should be a table of comma separated values including the iteration number n, xi, X2, X1, Xu, Xopt and the estimated error . a. Test the program for the function f(x) 12 x 2 x-1.5 x6 for the range xi 0 to xu 10. i. ii. Find Xopt and for an allowable error of 5%. Find Xopt and for an allowable error of 2%
