Observe the graph, solid line is drawn from “![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=74f3d3e4c40071d7ac71e61153308410.png\")
to left hand side” and
“4 to right hand side”.
\Therefore the inequality is,
\“Less than ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=74f3d3e4c40071d7ac71e61153308410.png\")
” or “greater than 4”.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/step2.JPG\")
Solid circles are used at and circle is used at 4.
So, is not included and 4 is not included in the solution.
The compound inequality is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=de4028b1229770eaede7ee686ec828b0.png\")
