Find the domain of the function coordinates.
\Here, ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=8da2268e35b6b6daab9c47f71c4c8bf4.png\")
-coordinate represents domain of the function in the graph.

-coordinate represents range of the function in the graph.
Therefore, the domain of the function is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=a2e25092161db9cda80d3fb095968cf7.png\")
