# Find the limit, if it exists. Limit as x approaches -8 of (8 - absolute x)/(8 + x).

## Question:

Find the limit, if it exists.

{eq}\lim_{x\rightarrow -8}\frac{8 - \left | x \right |}{8 + x} {/eq}.

## Limits with Absolute Values:

To find limits involving absolute values, we must be careful to keep our right and left limits straight. Thankfully, our limit is easy to work with, so all we need to do is think about our situation and get rid of the absolute value.
