Observe the graph, the graph has closed circle and the blue arrow (arrow solution) represent left side direction from ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=8e9410cb24eb265b31973313631a9c2b.png\")
.
The closed circle means that ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=8e9410cb24eb265b31973313631a9c2b.png\")
is a solution of the inequality. Because the arrow points to the left, all numbers less than are solutions.
The inequality represented by the graph is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=b13fd3602eccd6acbf8a7fefa1164a0b.png\")
