This abstract algebra problem seems trivially easy. Did I overlook something?

    1. The problem statement, all variables and given/known data

    The problem seems too easy so I suspect that I am overlooking something important. A problem this easy would be completely out of character for my professor...

    You've shown it's a homomorphism, but it asked you to show it's an isomorphism.

    Whoops! That's a typo. I typed the question wrong in latex. The problem on the assignment sheet says homomorphism.

    So assuming that the problem is asking for a homomorphism, does it look legit?
