Use (a) fixed-point iteration and (b) the Newton-Raphson method to determine a root off(x) = - 0.9x + 1.7x + 2.5 using xo = 5. Perform the computation until Ea

is less than Es =0.01%. Also, check vour final answer. (Problem 6.2 in the Applied Numerical Methods textbook, and problem 6.3 in the Numerical Methods for Engineers textbook.)
