How do you find the domain of #f(x)=sqrt(x+4)#?
Since you have a square root, the function it contains needs to be greater than or equal to zero:

To find the domain of ( f(x) = \sqrt{x+4} ), set the expression under the square root greater than or equal to zero:
[ x + 4 \geq 0 ]
Solve for ( x ):
[ x \geq -4 ]
So, the domain of ( f(x) ) is all real numbers greater than or equal to -4.

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.
