Suppose to solve for a root of f(x), i.e., f(x*) = 0, we use the iteration
Xk+1 = ¢(xk)
where o(x) and f(x) given functions with as many continuous derivatives as you require.
Show that if |O'(x*)| < 1 then for |xo – x*| sufficiently small the iteration xk+1 =
produces a sequence that converges to x*.
Note that the iteration ø(x) is called a contraction mapping in the neighborhood of x*
when |ø'(x*)| < 1.
