I'm having some trouble trying to come up with a way to do this. I have a range of numbers derived from a statistical analysis about a return on investment that falls between 0 and infinity. I am trying to reduce these numbers so they fall between either 1 and 1 or 0 and 1. I managed to do it with the numbers that are 1 and over, as I can simply take 1/(number), but I can't find a way to do it uniformly as when I do 1/(number < 1) it comes out as above 1. Any help that you could provide would be greatly appreciated! Thank you.

$1 \over 1 + x$?

$$y={12x \over 1+2x}$$

$$x1 \over x+1$$ may suit you better.

I would like you notice that what you are asking is not a real question because if you don't ask any particular property to the function then you can just take f(x)=0 and you are done. And you can find whatever function you want with just those properties if you don't ask for some kind of regularity.
