Kennedy AdamsThe domain of the function ( y = \sqrt{9 + x} ) is all real numbers where ( 9 + x ) is non-negative, so the domain is ( x \geq -9 ). The range is all real numbers where ( y ) is non-negative, so the range is ( y \geq 0 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
