To evaluate the limit of (x^2-16)/(x+4) as x approaches -4, we can substitute -4 into the expression and simplify. By substituting -4 for x, we get (-4^2-16)/(-4+4), which simplifies to (16-16)/0. Since we have a denominator of 0, this indicates that the limit does not exist.

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.
