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 $\phantom{\rule{thickmathspace}{0ex}}f(\mid x\mid )$,
$\phantom{\rule{thickmathspace}{0ex}}\mid f(x)\mid $, or even $\phantom{\rule{thickmathspace}{0ex}}f(\mid x\mid )+1$, 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.
