The function is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=a72733d1b1782bd336b52649186ce8db.png\")
.
a.Degree of the function.
\Since it is odd degree polynomial function.
\b.Find the end behavior.
\Since end behavior is in same opposite direction with leading coefficient is negative.

c.Find the number of real zeros.
\There are two ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=8da2268e35b6b6daab9c47f71c4c8bf4.png\")
-intercept and it has one real zero.
Therefore the polynomial function matches with the graph C.
