The function is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=071a49dd562f48dd2e02eac38fa82018.png\")
.
a.Degree of the function.
\Since it is even degree polynomial function.
\b.Find the end behavior.
\Since end behavior is in same direction with leading coefficient is positive.

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 two real zero.
Therefore the polynomial function matches with the graph A.
