(a) Prove that if X is path-connected and f: X Y is

(a) Prove that if X is path-connected and f: X Y is continuous, then the image f(X) is path-connected. (b) Prove that path-connectedness is a topological property, i.e. if X and Y are homeomorphic topological spaces, then X is path-connected if and only if Y is path-connected. Hint: Use (a) and note that it suffices to show one direction, then reverse the names X Y.
