3. Let S SR. Suppose {{n} and {9n} are sequences of functions such that fn + f uniformly on S and 9n →g uniformly on S. (a) Suppose for is bounded on S for each n E N. Then show that {fr} is uniformly bounded on S, which means that there exists M ER such that fn() < M for all re S and for all neN. (b) Prove that fn +n + f +g uniformly on S. (e) Prove that if fn and 9n are bounded on S for each n e N, then fn9n fg uniformly on S. n
