3. Write a MATLAB program that accomplishes the following using vectorized code (the variables used are vectors) Creates an x vector with elements from 1 to 10 in steps of 0.5, Creates a y vector from the equation y-#x2-3x + 5, Modifies the y vector by randomly adding or subtracting 0.6 to every element in the y vector Fits a quadratic equation through the data points given by the x and modified y vectors using least-squares approximation. Plots the (x, modified y) data points as green squares and the quadratic that was fit through these points as a blue line, and Puts the quadratic equation that was fit through the points as the title of the plot. Label the axes appropriately as well a. b. c. d. e. f. Turn in your m files and the plot
