3. In this problem we study another approach to show that certain equations have a unique solution on an interval [a, b]. The goal is to first write the equation in the form x = f(x) for some function f defined on [a, b]. (a) Suppose that f is continuous on [a, b] and that a < f(x) < b for all x € [a, b]. Prove that there exists c = (a, b) such that c = f(c). Hint: Consider the function g(x)= x-f(x).
