Question

Write a Matlab script to complete the following:

1. Write a script file that allows a user to: a. Plot a function from a list b. Change the function coefficients c. Choose function range and number of points d. Replot a new function on the same graph keeping the original function e. Replot a new function on the same graph overwriting the original function f. Save the graph (as a png file) Functions to choose from: y A sin(Bx + C)+ D y Asin2 (Bx C) + D y=Ax3 +Bx2 + Cx + D y-A exp(Bx C) + D
