The relation is express, the relation as ordered pairs
Draw a table with two columns and list the x-coordinates in the first column and
\y-coordinates.in the second column.

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
This is not a function because 3 in the domain has paired with four range values.
\Therefore the relation is not a function.
No.
