What is the domain of #f(x)=(x-2)/(x+4)#?
The domain is anything besides -4.
This indicates that x can be any value other than -4 since if x were -4, the denominator would be 0. If the denominator was 0, the formula f(x) = No Solution would apply.

The domain of the function f(x) = (x - 2) / (x + 4) is all real numbers except for x = -4, since division by zero is undefined. Therefore, the domain is (-∞, -4) ∪ (-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.
