Find the Domain of the Function $f ( x ) = \frac { 3 } { x ^ { 2 } }$

question 12

Short Answer

Find the domain of the function.
- $f ( x ) = \frac { 3 } { x ^ { 2 } }$
A) $\{ x \mid x < 2 \} , \text { or } ( - \infty , 2 )$
B) $\{ x \mid x > 3 \} , \text { or } ( 3 , \infty )$
C) all real numbers, or $( - \infty , \infty )$
D) $\{ x \mid x \neq 0 \} \text {, or } ( - \infty , 0 ) \cup ( 0 , \infty )$

• A) \(\{ x \mid x < 2 \} , \text { or } ( - \infty , 2 )\)
• B) \(\{ x \mid x > 3 \} , \text { or } ( 3 , \infty )\)
• C) all real numbers, or \(( - \infty , \infty )\)
• D) \(\{ x \mid x \neq 0 \} \text {, or } ( - \infty , 0 ) \cup ( 0 , \infty )\)
