Write a user-defined MATLAB function named PBTask4p1_f. m for the following math function with x the input argument and y the output: y(x) = 3.2x 4 − 5x 2 − 7x. The function should work for x being a scalar or a vector. Write a script file named PBTask4p1.m to a. Use the function to calculate y(-5) and y(4) and display the results in command window.
b. Use the function to make a plot of the function y(x) for -5 ≤ x ≤ 5.
