#### Answer

All real numbers where $ x \ne-4$.

#### Work Step by Step

We are asked to find the domain of the function here. In order to solve this problem, we look for things in the function which may limit its domain, such as square roots, log functions, and dividing by 0. We note that for this function, $x=-4$ results in a divide by 0 error, meaning that -4 is not included in the domain.
