6.2 Determine the highest real root of f(x)=2.1x311.6x2+17.5x6 (a) Graphically (b) Fixed-point iteration method (three iterations, x0=3 ). Note: Make certain that you develop a solution that converges on the root. (c) Newton-Raphson method (three iterations, x0=3 ). (d) Secant method (three iterations, x1=3,x0=4 ). (e) Modified secant method (three iterations, x0=3,=0.01)
