Pairs of points are $\"\"$ .

Plot the order of pairs on coordinate plane.

$\"graph$

$\"\"$

The relation is $\"\"$

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 $\"\"$ $\"\"$

Draw the vertical lines through the points. Observe that one vertical line passing through all points. This graph fails the vertical line test. Therefore the relation is not a function. $\"graph$

No.
