Let X = {(x, y) ∈ R2: x ≥ 0 or y = 0}; and let τ be the subspace topology on X induced by the usual topology on R2 . Suppose R has the usual topology and we define f : X → R by f((x, y)) = x for each (x, y) ∈ X. Show that f is a quotient map, but it is neither open nor closed.(So, a restricted function of an open function need not be...

According to Tietze's extension theorem, if (X,T) is a normal topological space, Y CX is closed, and f:Y → R is a bounded continuous function, then f can be extended to a bounded continuous function 9: X → R such that gly = f. Does the theorem continue to hold if Y is open (rather than closed)? Provide a proof or a counterexample.
