comment Finite Subgroups of Multiplicative Group of Field
The number of co-prime integers with n which are less than or equal to n. So we want values of n so the degree is 2 or less, which are precisely 1, 2, 3, 4, 6. Thanks Chris

comment Finite Subgroups of Multiplicative Group of Field
There are cyclic subgroups of $\mathbb C$* for any integer n. This can be seen by taking the generator to be the $n^{th}$ root of unity.

$ f(1) = 0 $ as $ f(1) = f(1/1) $ and each $f(1/k) = 0$

comment Identity Theorem
Thank you very much. I was trying to consider a power series but (stupidly) couldn't see which sequence $z_n$ to take so I could apply the identity theorem.
