Observe the figure 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 
Inverse: Exchange x and y in each ordered pair and write the inverse of the relation
