I couldn't find what I need from google, so I figured it's time to ask here.

Basically I'm looking for something like an online catalogue for all kinds of function graphs. I need a few specific ones and it wouldn't hurt to look for other options in case I don't find what I'm looking for.

If someone's wondering, I need those for image manipulation algorithms.

Just functions, or curves in general? –  Guess who it is. Jan 1 '12 at 12:06
Functions I think. Can you give me an example for a curve, just to see if I get the difference? –  Nikolay Dyankov Jan 1 '12 at 12:11
For curves in general, this and this (en français) are the online catalogs I usually consult. For books, there's von Seggern and Shikin. –  Guess who it is. Jan 1 '12 at 12:15
