\[f(x)=\sqrt{x}-9 ?\] just remember you don't want negatives under the square root part

so you want the thing inside the square root to be positive or zero if something is positive it is greater then 0 if something is zero it is equal to 0 so if something is positive or zero then it is >=0. so if the function really is f(x)=sqrt(x)-9 then the domain is easy to find if you meant f(x)=sqrt(x-9) then the domain is still easy to find you just have to do a little solving ...since remember you want x-9 to be positive or zero
