1. Write a user-defined MATLAB function for the following math function: y(x) = 0.6x³-0.47x +1.5x²e-0. The input to the function is x and the output is y. Write the function such that x can be a vector (use element-by-element operations). (a) Use the function to calculate y(-2) and y(4). (b) Use the function to make a plot of the function y(x) for -4≤x≤8.
