1. The problem statement, all variables and given/known data Find the inverse of the function: Y=X2-X, X≥½ 2. Relevant equations 3. The attempt at a solution I've switched X and Y to get: X=Y2-Y Then I've tried several things to get Y alone, but none of them seem to work. I've tried taking a square root, using a log, and several other things. I think using a log is the way to go here, but I can't seem to get it correct. I'm in the tutoring center here on campus and not even the tutors seem to be able to do it. I'd post my work, but I've gone through a half-dozen different ways of doing it and all of them come out to a dead end as far as I can tell, so I'm not sure what I'd post. Also, what's the significance of X≥½? Is it just extra info that I don't need? I know it limits using the function to only when X is equal to or greater than a half, but is that it? Thanks.
