Find the domain of the rational function.
-$$g ( x ) = \frac { x + 9 } { x ^ { 2 } + 1 }$$
A) all real numbers
B) $\{ x \mid x \neq - 1 , x \neq 1 , x \neq - 9 \}$
C) $\{ x \mid x \neq 0 , x \neq - 1 \}$
D) $\{ x \mid x \neq - 1 , x \neq 1 \}$

The denominator $x^2 + 1$ is always positive for all real x, so there are no restrictions on the domain.
