Using Matlab, write the following code

Make a plot with the curves y = kx2 5cos(x) + 4 in the range of 1 x 7 for 4 different values of k: k =1, 2, 3, and 4 (x is in radians). Try to write a function to calculate y as a function of x and call that from the main script. Try to use a for loop to go through the 4 values of k. You must include a legend, a title, and axes labels.
