et f: [a, b] → R be a function, where a and b are real numbers with a < b. (a) Prove that if f is continuous, then for any sequence {n} in [a, b] there exists a subsequence {n} such that {f(xnk)} converges. (b) Now suppose, instead, that f is bounded. Is it true that for any sequence {n} in [a, b] there exists a subsequence {n} such that {f(x)} converges? Prove or disprove.
