Find the domain of the function.
-$$f ( x ) = x - \frac { 5 } { x + 9 }$$
A) $( \infty , \infty )$
B) $( x , 5 )$ or $( 5 , \infty )$
C) $( \infty , - 9 )$ or $( - 9 , \infty )$
D) $( \infty , 0 )$ or $( 0 , \infty )$

Quizplus · Accepted Answer

The domain of the function is all real numbers except where the denominator equals zero. Since the denominator is $x + 9$, it equals zero when $x = -9$. Therefore, the function is defined for all $x$ except $x = -9$, which corresponds to $(-\infty, -9)$ and $(-9, \infty)$.
