Function draw
--- Introduction ---

**Function draw** is an exercise on the graphic
recognition of functions of one real variable.
The server will give you the graph of a function f(x), whose expression will
be hidden. Then with the help of a java applet, you are asked to draw the
graph of another function such as f(-x), 2f(x), f(x-1), etc
(see the menu below), with the mouse. You will have a score according to the
precision of your drawing.
