6. Let f,g: R→ R. be continuous functions and define S = {r ER: f(x) = g(x) = Z}, where Z stands for the set of all integers. Let (n) be a convergent sequence in S and let z = limn→∞ n. Can we say that ES? Would your answer change if we replace Z with the set Q of all rational numbers? Justify your answer.
