The domain of the relation is the set of all first (x-coordinates) coordinates.
\The domain of the relation is ![\"\"](\"/MathKey/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=a5f1da11de0ffd07dbd518e4e144e88d.png\")
The range of the relation is the set of first (y-coordinates) coordinates.
