Since end behavior is in opposite direction with leading coefficient is negative.
\b.Degree of the function.
\It is odd degree polynomial function.
\c.Find the number of real zeros.
\There is one ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=8da2268e35b6b6daab9c47f71c4c8bf4.png\")
-intercept and it has one real zero.
