A) $f ( s ) = \frac { 3 } { s + 3 }$
B) $f ( s ) = \frac { s } { x + 3 }$
C) $f ( s ) = \frac { s } { s - 3 }$
D) $f ( s ) = \frac { x } { s + 3 }$
E) $f ( s ) = \frac { s } { s + 3 }$

To find $f(s)$, substitute $s$ for $x$ in the function $f(x) = \frac{x}{x+3}$, resulting in $f(s) = \frac{s}{s+3}$.

If f(x)=xx+3f ( x ) = \frac { x } { x + 3 }f(x)=x+3x​
