If f(x)=(x-B)/(x=A) and f(2)=0 and f(1) is undefined what is A and B?

If f(2) is 0 then that means the top is 0 so 2 - B is 0. Which means B is ...? If f(1) is undefined, that means the bottom is 0 so whatever the bottom was supposed to be is 0, which means A is ...?

We know that: and that is undefined. If f(1) is undefined, that means that we will be dividing by zero, such that . We can now substitute A for 1:
B=2, A=1? That's what I have as answers but I'm just checking.
