Gosh that's what happens when you dont read lol

For c) The only thing you need to show is that there exist a rational number u such that f(u) = something / (something + 1). I can't find the u .

Nice job I was pretty good at competition math back in high school, I think the best I ever did was 30th~ in the USAMO. There were certain classes of problems I always had trouble with, though, like geometry and inequalities. I've taken the Putnam twice so far, but I don't really practice much anymore.
