Best ResponseYou've already chosen the best response.1so 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(x9) then the domain is still easy to find you just have to do a little solving ...since remember you want x9 to be positive or zero
