Ok, for non-math students, here's a small tutorial: f(x) = 3x means, if we have x, we can find f(x). also, this function is invertible, since we can say x = f(x) / 3 we'd write this as f^-1(y) = y/3 (that's f inverse y). so if we know f(x), we can find out x. Some functions however, are not invertible, like f(x) = x^x (at least I think it is non-invertible). Thus, if you have x, you can get f(x), but if you have f(x), you cannot get x. > P.S. > 3.22am ?? :) Post party time. It's funny what a couple of beers can do. -- "How do I love thee?
