## Image

The image provided could use labels denoting where a and b are located on the x axis and a little more on the meaning of A. How is A defined?RRphys 14:35, 28 September 2007 (UTC)

I've replaced the old image with a new SVG one for easier editing. I've added labels on the y-axis, but I'm also not entirely sure where a and b labels should go, so I left those out for now. If anyone lets me know I can add them to the diagram easily. --Qef (talk) 00:46, 2 July 2008 (UTC)
a is the x-axis label for the left-most part of the function when the function when it equals the value A. b is the x-axis label for the right-most part of the function when it equals A. That is,
${\displaystyle a=\arg \min _{x\in [a,b]}f(x)\,}$
${\displaystyle b=\arg \max _{x\in [a,b]}f(x)\,.}$
