Find the domain of the function. $$f ( x ) = \frac { 7 x + 1 } { x ^ { 2 } }$$
A) $( - \infty , 0 )$
B) $\left( - \infty , - \frac { 1 } { 7 } \right) \cup \left( - \frac { 1 } { 7 } , \infty \right)$
C) $\left( - \infty , \frac { 1 } { 7 } \right) \cup \left( \frac { 1 } { 7 } , \infty \right)$
D) $( - \infty , 0 ) \cup ( 0 , \infty )$

Quizplus · Accepted Answer

The function is defined for all values of $x$ except $x=0$ because dividing by zero is undefined. Therefore, the domain is $( - \infty, 0 ) \cup ( 0, \infty )$. Choice D matches this interval.
