    I'm doing a graphing activity using computers. I'll have my students explore linear equations, some quadratics and cubics as well. Just for fun, I'd like to give them a function that has a fun-looking graph. It can be a complicated one; I'll jsut have them type it in and graph it, they will not be analyzing it. Does anyone have any ideas?

    Thanks!

    are you just wanting single variable real valued functions?

    Do you have a membership to nctm? If so, you can search their archives.

    That's pretty cool, HMM. But, I DO want single variable real valued functions. I'm using a simpler program than wolframalpha, I'm using www.mathsisfun.com/data/function-grapher.php. It's simpler for my 7th graders, but it can't do the kind of piecewise relation that you had.

    Thanks, though! Any more ideas?
