The domain of the relation is the set of all first (x-coordinates) coordinates.
\The domain of the relation is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=00cc4d5be89094a4c74e90d05db83cb2.png\")

The range of the relation is the set of first (y-coordinates) coordinates.
\The range of the relation is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=5f75155664a4fc4fa7cce5205cb3c718.png\")

Each element of the domain is paired with exactly one element of the range. Therefore the relation is a function and this one-to-one function.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/solution.JPG\")
Yes the relation is a function.
