Multiple Choice

Find $g \circ f$ and the domain of the composite function.
$f ( x ) = \frac { 1 } { x } , g ( x ) = x + 5$

A) $\frac { 1 } { x + 5 }$ Domain of $g \circ f$ : all real numbers x except $x = - 5$
B) $\frac { 1 } { x } - 5$ Domain of $g \circ f$ : all real numbers x except $x = 0$
C) $\frac { 1 } { x } + 5$ Domain of $g \circ f$ : all real numbers x except $x = 0$
D) $- \frac { 1 } { x + 5 }$ Domain of $g \circ f$ : all real numbers x except $x = - 3$
E) $\frac { 1 } { x - 5 }$ Domain of $g \circ f$ : all real numbers x except $x = 5$
