Find the domain.
-$$f ( x ) = \frac { 7 } { x - 4 }$$
A) $\{ x \mid x$ is a real number and $x \neq - 4 \}$
B) $\{ x \mid x$ is a real number and $x \neq 7 \}$
C) $\{ x \mid x$ is a real number and $x \neq - 7 \}$
D) $\{ x \mid x$ is a real number and $x \neq 4 \}$

The function is undefined when the denominator is zero, which occurs when $x - 4 = 0$, or $x = 4$. Therefore, the domain is all real numbers except $x = 4$.
