(3) Let f: R→→ R be a differentiable function and that f has a bounded derivative. (That means there exists B > 0 such that |ƒ'(x)| ≤ B for all à € R.) (a) Show that f is uniformly continuous on R. (b) If B < 1, then there exists a unique fixed point of f. (Hint: consider a sequence xo, f(xo), f(f(xo)),... defined by repeatedly applying f to an arbitrary to € R.)
