Observe the graph, the graph containing two lines, one line starts from ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=46dffacddd1620bf16b27648692b4624.png\")
to negative infinity and here ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=46dffacddd1620bf16b27648692b4624.png\")
is including in the solution set since it is contain dot.
The remaining line starts from 6 to positive infinity and here 6 is including in the solution set since it contain dot.
\The graph shows the solution ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=b1559231e4a41990887ade4a66e1b670.png\")
