Determine Whether the Given Function Is One-To-One $$f ( x ) = \frac { 2 } { x + 3 }$$

Multiple Choice

Determine whether the given function is one-to-one. If it is one-to-one, find a formula for the inverse.
- $$f ( x ) = \frac { 2 } { x + 3 }$$

A) $f ^ { - 1 } ( x ) = \frac { - 3 x + 2 } { x }$
B) $f ^ { - 1 } ( x ) = \frac { x } { 3 + 2 x }$
C) $f ^ { - 1 } ( x ) = \frac { 3 + 2 x } { x }$
D) Not one-to-one
