f(x) = 1/x is just one example of a function that has the property of being a "negative function" -- the smaller number you put in, the larger number you get out, and vice versa. Your statement didn't clearly indicate that the outputs need to be bigger than the inputs, just that they need to be bigger the smaller the outputs are. The more general function would be f(x) = A/(x - B). Choose A and B as desired so that f(x) > x for all x you care about. Or choose another function, like f(x) = A - B x or any number of other functions. There literally are an infinite number of possibilities. The point is, as I've already said, you haven't given nearly enough information to give you a useful answer. You haven't indicated, for instance, anything at all about the domain or range of the function that you want: What values do you need to plug in? What range of values do you need to get out? Once you have clarified to yourself what properties you want, that will help you define the function. At this point you're the only one who knows what properties you want, and unless you define them up front, it results in a very unsatisfactory guessing game of proposing a function, you telling me what's wrong with it, and repeat until either or both of us get bored. And, by the way, this is a question about mathematics, and so has nothing to do specifically with Python. -- Erik Max Francis && [EMAIL PROTECTED] && http://www.alcyone.com/max/ San Jose, CA, USA && 37 20 N 121 53 W && AIM, Y!M erikmaxfrancis Get married, but never to a man who is home all day. -- George Bernard Shaw -- http://mail.python.org/mailman/listinfo/python-list
