Observe the graph:
\The graph intersects the ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=8da2268e35b6b6daab9c47f71c4c8bf4.png\")
–axis at ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=21389f289a3c9c5a71197b906ed5545d.png\")
and ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=d9285d5a293c4e12028128b0fb74ba46.png\")
.
The graph has only one turning point.
\Hence, the graph represents the function whose degree is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=d1622611fc88fa0fbe88f093bcb90f93.png\")
.
Therefore, function has two zeroes.
\In option ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=b72515eceac9b0f2954ec68f910b8672.png\")
, there are only two zeroes. \ \
Choice matches the graph.
