The relation is
\Express the relation as ordered pairs.{(9.2, 7), (9.4, 11), (9.5, 9.5), (9.8, 8)}
\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 {9.2, 9.4, 9.5, 9.5, 9.8}
\The range of the relation is the set of second (y-coordinates) coordinates.
\The range of the relation is {7, 11, 9.5, 8}![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/step3.JPG\")
Each element of the domain is paired with exactly one element of the range.
\Therefore the relation is a function.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/solution.JPG\")
Yes.
