Find the domain of the function.
-$$f ( x ) = \frac { - 3 x } { x - 8 }$$
A) $( - \infty , 8 ) \cup ( 8 , \infty )$
B) $( - \infty , \infty )$
C) $( - \infty , 0 ) \cup ( 0 , \infty )$
D) $( - \infty , 8 )$

The domain of the function excludes values of $x$ that make the denominator zero. Since the denominator is $x - 8$, setting it equal to zero gives $x = 8$. Therefore, the domain is all real numbers except $x = 8$, which is option A: $( - \infty , 8 ) \cup ( 8 , \infty )$.
