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 0 and 11 in the domain is paired with two range values 4,10 and 6,8.
\Therefore the relation is not a function.
No.
