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.
x |
y |
13 |

13 | 10 |
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 13 in the domain is paired with two range values 5 and 10.
Therefore the relation is not a function.
No.
