Observe the graph, the graph containing two lines, one line starts from ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=2af6e83b0e9af64878f4e8cc8c73d3f5.png\")
to negative infinity and here ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=2af6e83b0e9af64878f4e8cc8c73d3f5.png\")
is including in the solution set since it is contain dot.
The remaining line starts from 0 to positive infinity and here 0 is not including in the solution set since it contain circle.
\The graph shows the solution ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=c3d0412f974b54b53aff5cb776e76724.png\")
