Hello. I'm having a bit of trouble with a question I've been given as part of a Maths course, and was wondering if someone could help. 1. The problem statement, all variables and given/known data http://img21.imageshack.us/img21/4920/question6c.jpg [Broken] 2. Relevant equations http://img222.imageshack.us/img222/7092/equations6.jpg 3. The attempt at a solution http://img22.imageshack.us/img22/1508/attempt6.jpg As you can see, the function is meant to have +5 on the end, but I get -5. I don't know where I've gone wrong. I did ask the teacher if the 5/4 is just added to the y, and she nodded. I would appreciate any and all help with this. I know its basic, but its got me.
