Answer
Wyatt wrongly identify the domain and the range.
The domain is $(-\infty,\infty)$.
and the range is $\{8\}$.
Work Step by Step
The given function is
$f(x)=8$
This is a linear function.
Hence, all real number inputs will result in the single number $8$ output.
The domain is $(-\infty,\infty)$.
and the range is $\{8\}$.
