The solutions of the equation are the ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=8da2268e35b6b6daab9c47f71c4c8bf4.png\")
–intercepts of the graph.
Observe the graph:
\Consider the scale on the graph about -axis is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=1f27b4e66d9d3aa72e35b39517440674.png\")
.
The graph is intersect the –axis, hence the function has one –intercepts.
The zero of the equation is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=252a73ffa4e604e8978abd0e2a69d32b.png\")
