Solution: Given f (x) = 2x 3 - 2x - 5 = 0 As per the algorithm, we find the value of x o, for which we have to find a and b such that f (a) < 0 and f (b) > 0 Now, f (0) = - 5 f (1) = - 5 f (2) = 7 example To find the root of the function f (x)0. we need to follow the following steps. 1 Then the sequence of approximations x1,x2, x3xn will converges to the root a provides the initial condition x0 chosen in I 2 3 5 Algorithm for fixed point iteration.
