To find the domain of ( f(x) = \sqrt{x + 4} ), you need to identify the values of ( x ) for which the function is defined. Since the square root function is defined only for non-negative real numbers, you need to ensure that the expression under the square root, ( x + 4 ), is non-negative.
So, to find the domain:
( x + 4 \geq 0 )
( x \geq -4 )
Therefore, the domain of ( f(x) = \sqrt{x + 4} ) is all real numbers greater than or equal to -4, or in interval notation: ([ -4, \infty )).

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.
