Observe the graph:
\a. Find the end behavior.
\![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=cc01d43b42cdf024766a374fe1eaec3c.png\")
Since end behavior is in same direction with leading coefficient is negative.
\b. Degree of the function.
\Since it is even degree polynomial function.
\c. Find the number of real zeros.
