Help with Function problem
Question: X is the set of senators serving in 1998. For x ∈ X, define g(x) to be the number of terms a senator has held. Is g(x) a function?

Thanks for any help!

If you say "terms held by a certain date", then for every senator such number of terms is unique. If you just ask how many term a senator x served, the answer may be one, and two, and three...

Yes.
if x $\in X \Rightarrow$ g(x)=1. Because x is a senator, and a senator is a one senator.

Maybe you have a mistake went write the problem.
