The server will give you the graph of two functions $f$ and $g$, whose expressions will be hidden. You will then be presented a certain number of other graphs, corresponding to functions such as $f(x)+g(x)$, $f(-x)-g(x)$, $f(x)+g(-x)$, 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.

Please take note that WIMS pages are interactively generated; they are not ordinary HTML files. They must be used interactively ONLINE. It is useless for you to gather them through a robot program.

- Description: recognize the graph of f(x)+g(x) from that of f and g, etc. This is the main site of WIMS (WWW Interactive Multipurpose Server): interactive exercises, online calculators and plotters, mathematical recreation and games
