Ok, that is different. Let me try to help you again.

Question 1) Do you know/remember how to show something is a equivalence
relation? (hint: 3 things to check)

Question 2) How to check a ---> a/e is a homeomorphism? (hint: you need
to ensure it is well defined)

think about this two questions and then we can continue with this. It
is not too hard.
