You can put this solution on YOUR website! I'm not sure exactly what you mean by this. If you mean which is technically what you have given, it means that x must be greater than or equal to zero. Domain is in interval notation: [0, infinity)
If you meant , this means that x-2 must be greater than or equal to zero. If you add 2 to each side of the inequality, you get x must be greater than or equal to 2. Domain for this, in interval notation, would be [2, infinity).
