Determine Whether the Given Function Is One-To-One $$f ( x ) = \frac { 4 x - 7 } { 2 x + 6 }$$

Multiple Choice

Determine whether the given function is one-to-one. If so, find a formula for the inverse.
- $$f ( x ) = \frac { 4 x - 7 } { 2 x + 6 }$$

A) Not a one-to-one function
B) $f ^ { - 1 } ( x ) = \frac { 4 x - 7 } { 2 x + 6 }$
C) $f ^ { - 1 } ( x ) = \frac { - 6 x - 7 } { 2 x - 4 }$
D) $f ^ { - 1 } ( x ) = \frac { 2 x - 4 } { - 6 x - 7 }$
