--- Introduction ---
Graphic multiplication is an exercise concerning the
graphical recognition of the multiplication of functions of one real variable.
The server will give you the graph of two functions f(x) and g(x),
whose expressions will be hidden. You will then be presented a certain number of other graphs,
corresponding to functions such as
f(x)g(x), f(-x)g(x), f(x)g(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.
