Make a code by performing following steps a) Define a radius r with r = 2 b) Define a row vector x whose first element is -6, and the increment size is 0.04 and last element is 3. So, the first element will be -6, second element will be -5.9600 so on and so forth. c) Make a for loop that calculates (x)2 and saves it in a variable with name a, using array indexing i and then calculates (x)3 and saves it in another variable with name b using the array indexing i. d) Make a plot with x on x-axis and values of a plotted on y-axis. Make a plot with x on x- axis and values of b plotted on y-axis. There should be only one figure with two plots. Note: You will use only one for loop Please use Matlab to solve it
