Press the "New Rational Function" button to generate a random rational function. Can you determine the equation for this rational function? Type the equation into the input bar and press enter to see if you are correct.

You can either reload this page or press the "New Rational Function" button to get a new function. The random function is purple, and the function that you guess is dashed blue. Type another function into the input box for f(x) and press enter to guess a new function.[br][br]This activity is adapted from stcarranza's http://www.geogebratube.org/student/m334763 If this is too complex for you right now, try that one first!
