For the following function, determine the highest real root of f(x) = 2x3 – 11.7x2 + 17.7x - 5 by using (a) graphical methods, (b) fixed point iteration (three iterations, x0 = 3) (Hint: Be certain that you develop a solution that converges on the root), and (c) Newton-Raphson method (three iterations, x0 = 3). Perform an error check on each of your final root approximations (e.g. for the last of the three iterations).

Suppose we modify the bisection method into the following variation: for each step, with bracketing interval [a,b], approximations are chosen at the location (2a + b)/3, but the interval is cut into two at the different location (a + 3b)/4. (a) Calculate the first 2 approximations p1,p2 for this variation when f(x) = cosx−x with starting interval [0,π/2]. (b) Bound the absolute errors of the approximations pn for a starting interval of length L.
