Answer
The domain of the function is the set of all real numbers except $-8$.
Work Step by Step
When the question asks for the domain of the function, it is asking for what values of x can be legally substituted into the function. (For instance, in the function $\frac{2}{x}$, x $\ne$ 0, for this would make the denominator of the fraction equal to 0.)
In the given function, any real number except $-8$ can be substituted for the variable $x$.
When $x$ is replaced by $-8$, the denominator becomes 0, which makes the function undefined.
Thus, the domain of the function is the set of all real numbers except $-8$.
