The statement is False.
\Explanation :
\When the second derivative is less than ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=fcd348ebf66f4047fc23f05f2c058874.png\")
, it means that the function ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=7638897a5bb9204998d7996637c7b50a.png\")
is concave down.
This means that the function ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=7638897a5bb9204998d7996637c7b50a.png\")
increases and then decreases.
It does not mean that the function decreases without bound.
\Therefore the statement is false.
