Some of these functions are just an insane calculation mistake waiting to happen. Mult-regressed functions with eighty to ninty sub calculations? That is insane. I have never seen any this convoluted before, and this 4th or 5th one, whatever, is about the hardest I have seen in any of three college algebra textbooks. The others before this question were murder, making it exeptionally hard for anyone to get out of this without punishment for a stupid math mistake.
