Observe the graph :
\a. Find the end behavior.
\![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=bf1ecba2bfd18b9c9ba7342b4b78a182.png\")
Since end behavior is in opposite direction with leading coefficient is positive.
\b. Degree of the function.
\It is odd degree polynomial function.
\c. Find the number of real zeros.
\There are one ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=8da2268e35b6b6daab9c47f71c4c8bf4.png\")
-intercept and it has one real zero.
