Graphic abs is an exercise concerning the
graphical recognition of functions of one real variable involving absolute
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|),
|f (x)|, or even |f (x)|+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.
