. Using the program of Problem 5, solve the equation f(x) , x3-3x2 + 3x-1 = 0 with an accuracy of-10-6. Experiment with different ways ofevaluating f(x) for example, use () the given form,(i) reverse its order, and (ii) the nested form f(x) =-1 + x (3 + x (-3 + x)) Try various initial intervals la, b], for example, [0, 1.5], [0.5, 2.0], and [0.5 Explain the results. Note that = l is the only root of f (x) = 0
