.
The degree of polynomial is even (n = 2) and leading coefficient is positive (![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=11fbb1955971f163be96dbfb8b7166e8.png\")
).
Since the function is an even function and it has positive leading coefficient, the graph rises to the left and right.![\"\"](\"/userfiles/image/steps_images/solution.JPG\")
The graph rises to the left and right.
