2. Let f(x) be a continuous function on the interval [0, 1], and suppose 0≤ f(x) ≤ 1 for all x = [0, 1]. (a) There exists a point xo in [0, 1] such that f(xo) = xo. A point with this property is called a fixed point. (Hint: consider the function g(x) = f(x) = x.) (b) Must there exist a point xo in [0, 1] such that 2f (ro) = xo? Either prove that the answer is yes, or give an example of a function f for which this is not true.
