Ok. Note that vanishes when x equals 0 or 18. Note also that is an equation of a parabola with a global minimum. That mean that when U , that's your domain.

EDIT: I'm sorry in my first post, it should be "The domain is all the that make ." - Aug 20th 2008, 07:38 PMsadieann

A pleasure to help. I understand you were in a rush but when you have time, try to understand what I did and ask us if you don't understand. Good luck.
