Question 1107502: give the domain and range of f(x) = square root of x-4
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
Domain is any x > =4. The square root of (x-4) is not real if x is less than 4.
The range is (0, +oo)
The sqrt can't be negative, but as x becomes infinite, the square root goes to infinity as well.
