The parent function for a square root graph points from 0 to infinity.

The function you have given will be moved 5 to the right, because -5 inside the square root means move 5 to the right.

So, everything else remains the same and the domain is 5 to infinity.

Other ways to write it are [5,∞] or x ≥ 5
