-$$f ( x ) = \frac { 1 } { x - 9 }$$
A) $( 9 , \infty )$
B) $( \infty , \infty )$
C) $( \infty , 0 )$ or $( 0 , \infty )$
D) $( \infty , 9 )$ or $( 9 , \infty )$

The domain of the function $f(x) = \frac{1}{x-9}$ consists of all real numbers except for $x = 9$, because at $x = 9$, the denominator becomes zero, which makes the function undefined. Therefore, the domain is all real numbers except 9, which is represented as $(-\infty, 9)$ union $(9, \infty)$.
