Consider finding the root of a given nonlinear function f(x), known to exist in a given interval [a,b), using one of the following three methods: bisection, Newton, and secant. For each of the following instances, one of these methods has a distinct advantage over the other two. Match problems and methods and justify briefly. (a) f(x) =x - 1 on the interval [0,2.5]. (b) f(x) is given in Figure 3.5 on [0,4]. (c) fe C°[0.1,0.2], the derivatives of f are all bounded in magnitude by 1, and f'(x) is hard to specify explicitly or evaluate.
