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.\"\"
