Express the relation as ordered pairs
The domain of the relation is the set of all first (x-coordinates) coordinates.
\The domain of the relation is .
The range of the relation is the set of second (y-coordinates) coordinates.
\The range of the relation is .
Each element of the domain is paired with exactly one element of the range.
\Therefore the relation is a function.
Yes.
