Answer
$\text{all real numbers except }$ $
n=16
$
Work Step by Step
$\bf{\text{Solution Outline:}}$
The domain of the given rational function, $
p(n)=\dfrac{n+8}{n-16}
,$ are the values of $
n
$ which will NOT make the denominator equal to $0.$
$\bf{\text{Solution Details:}}$
Solving for the values of $
n
$ that will make the denominator equal to $0$ results to
\begin{array}{l}\require{cancel}
n-16=0
\\\\
n=16
.\end{array}
Hence, the domain is the set of $
\text{all real numbers except }$ $
n=16
.$
