Find the implied domain of f(x)= (square root x-5) + (square root 15 -x) or (x-5) ^(1/2) + (15 -x)^(1/2) Sorry I don't know how to use the square root sign here.

Hi $\displaystyle f(x) = \sqrt{x-5} + \sqrt{15-x}$ You can take the square root of only positive expressions You must have both $\displaystyle x-5 \geq 0$ and $\displaystyle 15-x \geq 0$
