Find the composite function $f ( g ( x ) )$ . $f ( u ) = \frac { 1 } { u }$ , $g ( x ) = x + 3$
A)f (g(x))= $1 + \frac { 3 } { x }$
B)f (g(x))= $\frac { 1 } { x + 3 }$
C)f (g(x))= $x + 3 + \frac { 1 } { x }$
D)f (g(x))= $\frac { 1 } { x } + 3$

Quizplus · Accepted Answer

To find the composite function $f(g(x))$, substitute $g(x) = x + 3$ into $f(u) = \frac{1}{u}$, resulting in $f(g(x)) = \frac{1}{x + 3}$.
