Hello I was wondering if someone could check my working and answers to these three homework questions. I've done the inverse functions in class, but not the composite inverse functions, if that's what they're called. 1. The problem statement, all variables and given/known data http://img24.imageshack.us/img24/6035/question4t.jpg [Broken] 2. Relevant equations http://img25.imageshack.us/img25/2204/equations4.jpg [Broken] 3. The attempt at a solution http://img27.imageshack.us/img27/3402/attempt4a.jpg [Broken] http://img27.imageshack.us/img27/9500/attempt4b.jpg [Broken] I'd appreciate any feedback. Parts a and b are just like I've done in class. Where I've left them is where we ended them in class. Part c is just a guess. I don't know if there is a special rule or something like that. Thanks.
