Then * f is continuous but it is not a homeomorphism None of the choices f is not continuous f is a homeomorphism Let X and Y be two discrete spaces, then * X is homeomorphic to Y if and only if X and Y are both finite X is homeomorphic to Y if and only if X and Y have the same cardinality X is never homeomorphic to Y X is homomorphic to Y if and only if X and Y are both infinite
