Assuming your student ID number is of the form erB", you will use the value B in the sequel. If Bis zero, then take it as 1. Q1. Write a MATLAB implementation that takes the number of data points n (which is not less than 3) as input: creates arrays for r and y values of the data points and asks user to enter these values, constructs the best parabola f (t) = ax? +bu + c and gives it as the output. You cannot use the command polyfit
