9. (c) The graph of the Newton function. |
(d) The graph of the Newton function does not intersect the diagonal line, so there are no (real) fixed points for Newton's method. |
(e) The first ten iterates of Newton's method, starting from x = 0.333, are -1.335, -0.292969, 1.56018, 0.459613, -0.858065, 0.153674, -3.1768, -1.43101, -0.366101, 1.18269 |
(f) The first ten iterates of Newton's method, starting from x = 0.334, are -1.33001, -0.289065, 1.58518, 0.477171, -0.809258, 0.213221, -2.23837, -0.895808, 0.110252, -4.47996 |
(g) This suggests Newton's method for this function exhibits sensitive dependence on initial conditions. |
