Thank you!

Can you help me and for this exercise please! the function f:(X,T)->(X,T') is continuous the function f:(X,T')->(X,T) is open {T is the Euclidean topology,T' is cofinite topology} [the function f maybe is the identity function id but I am not sure]

thank you! U had helped me a lot thanks thanks

please can you help me to prove this exercise; Prove that: the Euclidean topology R is finer than the cofinite topology on R please answer me as faster as u can I have an exame on monday and I don't know to provethis exercise!
