# Graphic abs --- Introduction ---

Graphic abs is an exercise concerning the graphical recognition of functions of one real variable involving absolute values.

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 $f\left(x\right)$ such as $\phantom{\rule{thickmathspace}{0ex}}f\left(\mid x\mid \right)$, $\phantom{\rule{thickmathspace}{0ex}}\mid f\left(x\right)\mid$, or even $\phantom{\rule{thickmathspace}{0ex}}f\left(\mid x\mid \right)+1$, etc (see the menu below). And you should cocate 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.

Set up
