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 .
This is not a function because 5 and 2 in the is paired with two range values 4,14 and 8,12.
\Therefore the relation is not a function.
No.
