![Problem 2. Consider the space C(R, R) of continuous real-valued functions.
(a) Given any ƒ € C(R,R), show that there exists a sequence of polynomials (Pn)n that converges
pointwise to f, i.e. limn→∞ Pn(x) = f(x) for every x ₹ R.
(b) Show that one can moreover choose the sequence (Pn)n in such a way that the convergence is uniform
on any compact subset of R, i.e. for every KCR compact, Pn → ƒ uniformly on K. (Note: the
