Prove or provide a counterexample

If f is T_C−T_U continuous, then f is T_U−T_C continuous.

Where T_C is the open half-line topology and T_U is the usual topology.

Let (X,dX),(Y,dY ) be metric spaces and f: X → Y be a continuous bijection. Prove that if (X, dX ) is compact, then f is a homeomorphism. (Hint: it might be convenient to use that a function is continuous if and only if the inverse image of every open set is open, if and only if the inverse image of every closed set is closed).
