Find the domain of the function.
-$$f ( x ) = \frac { x } { x ^ { 2 } + 19 }$$
A) $( - \infty , \infty )$
B) $( - \infty , - 19 ) \cup ( - 19 , \infty )$
C) $( - 19 , \infty )$
D) $( - \infty , 0 ) \cup ( 0 , \infty )$

Quizplus · Accepted Answer

The denominator $x^2 + 19$ is always positive for all real x, so there are no restrictions on the domain.
