Graphic functions
--- Introduction ---

Graphic functions is an exercise concerning the graphical recognition of
functions of one real variable. The server will give you the graph
of a function *f* (x), whose expression will be hidden. You will
then be presented a certain number of other graphs, corresponding
to modifications of
*f* (x) such as *f*(-*x*), 2 *f*(*x*), *f*(*x*-1), etc (see the menu below).
And you should locate the one which corresponds to one which will
be precised in a question. To give the reply, you can simply click on
the graph which you believe to be the good one.
