Function.
\Yes;
\Because each element of the domain is paired with one element of the range. \ \
\One -to-one function.
\Yes;
\Each element of the domain is paired with exactly one element of the range.
\Onto:
\Yes;
\Because each element of the range corresponds to an element of the domain.
\Therefore, the relation is a function.
