Short Answer

Find the domain of the function.
- $f ( x ) = 6 - \frac { 4 } { x }$
A) $\{ x \mid x > 6 \} \text {, or } ( 6 , \infty )$
B) $\{ x \mid x < 4 \} \text {, or } ( - \infty , 4 )$
C) all real numbers, or $( - \infty , \infty )$
D) $\{ x \mid x \neq 0 \} \text {, or } ( - \infty , 0 ) \cup ( 0 , \infty )$
