computational method course

please answer the bonus (E) only as simple as possible

Problem 2: Show all your calculations in order to get a full credit. 6.2 Determine the highest real root of ((x) = 2 1x' -11.6x-+17.5x-6 (a) Graphically. (b) Fixed-point iteration method (three iterations, x. = 3). Note: Make certain that you develop a solution that converges on the root. (c) Newton-Raphson method (three iterations, x = 3). (d) Secant method (three iterations, r = 3, x, 4). (e) Bonus: Modified secant method (three iterations, t, = 3, d = 0.01). Compute the approximate percent relative errors for your solutions
