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.
