Observe the graph:
\a. Find the end behavior.

Since end behavior is in same direction with leading coefficient is positive.
\b. Degree of the function.
\Since end behavior is in same direction, it is even degree polynomial function.
\c. Find the number of real zeros.
\Since there are no ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=8da2268e35b6b6daab9c47f71c4c8bf4.png\")
-intercepts and it has no real zero.
