Observe the graph:
\a.
\Find the end behavior.
\![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=4cfbbe72451f7633bb8a3daa6058fa28.png\")
Since end behavior is in same direction, the leading coefficient is positive.
\b.
\Degree of the function.
\It is even degree polynomial function.
\c.
\Find the number of real zeros.
\The function does not touches the ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=8da2268e35b6b6daab9c47f71c4c8bf4.png\")
-axis.
There are no -intercept and it has no real zero.
![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/solution.JPG\")
End behavior is in same direction.
\It is even function.
\It has zero real zeros.
