Using Matlab Please (code answer!), thanks.

1. Fixed Point Method, Newton-Raphson Method, & Secant Method Determine the highest real root of f(x) = 2x3 11.7+17.72 - 5: - Graphically (Just for checking out) - Use fixed point iteration method (three iterations, 20 = 2.9). - save the root on HW4-1.dat file - save the estimated error Eq on HW4-2.dat file - show all steps of three iterations by hands. (use an engineering paper.) - Newton-Rapson method (three iterations, to = 2.9). - save the root on HW 4-3.dat file - save the estimated error Ea on HW4-4.dat file - show all steps of three iterations by hands. (use an engineering paper.) - Secant method (three iterations, 2-1 = 2.9, 20 = 4). - save the root on HW4-5.dat file - save the estimated error Eq on HW4-6.dat file - show all steps of three iterations by hands. (use an engineering paper.) - Modified secant method (three iterations, to = 2.9, 8 = 0.2). - save the root on HW4-7.dat file - save the estimated error Eq on HW4-8.dat file - show all steps of three iterations by hands.
