() = 0 one finds Newton’s method takes 20 iterations and the secant method takes 30. When is it possible that the secant method takes less computing time? Make sure to explain your answer.

(b) Which of the curves in Figure 2.20 corresponds to Newton’s method and which one to the bisection method? Make sure to justify your answers.
