Observe the graph, the graph has open circle and the blue arrow (arrow solution) represent right side direction from 4.
\The open circle means that 4 is not a solution of the inequality. Because the arrow points to the right, all numbers greater than 4 are solutions.
\The inequality represented by the graph is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=5ab84600c9cd7a4a0ca5dcc313582914.png\")
