Let (fn)1 be a sequence of bounded real-valued functions on X. (a) If fn f on X, show that f is bounded on X. (b) If (n)-1 converges pointwise to a bounded function f on X, must the convergence be uniform? Justify. Note: The function h: X→→→→ R is bounded if and only if there exists M >0 such that h(x)| ≤ M for all x € X.
