# 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), 2f (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.

The exercise can be configured by the following parameters.
• Type of variations of the function:
1. f (-x), -f (x), -f (-x) ;
2. f (x1), f (x)1 ;
3. f (2x), f (x/2), 2f (x), f (x)/2 ;
4. f (x1), f (x)1 ;
5. f (2x), f (x/2), etc...
• Numbre of questions in one session: , , , , , , , (The score is attributed only at the end of a session.)
• or you can be asked to recognize each presented curve.
