# 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 $f\left(x\right)$, whose expression will be hidden. You will then be presented a certain number of other graphs, corresponding to modifications of $f\left(x\right)$ such as $f\left(-x\right)$, $2f\left(x\right)$, $f\left(x-1\right)$, 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. $f\left(-x\right)$, $-f\left(x\right)$, $-f\left(-x\right)$ ;
2. $f\left(x±1\right)$, $f\left(x\right)±1$ ;
3. $f\left(2x\right)$, $f\left(\frac{1}{2}x\right)$, $2f\left(x\right)$, $\frac{1}{2}f\left(x\right)$ ;
4. $f\left(±x±1\right)$, $±f\left(x\right)±1$ ;
5. $f\left(±2x\right)$, $±f\left(x/2\right)$, etc...
