Determine Whether the Given Function Is One-To-One $$f ( x ) = 4 x - 3$$

Multiple Choice

Determine whether the given function is one-to-one. If so, find a formula for the inverse.
- $$f ( x ) = 4 x - 3$$

A) $f ^ { - 1 } ( x ) = \frac { x + 3 } { 4 }$
B) $\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \frac { \mathrm { x } } { 4 } + 3$
C) Not a one-to-one function
D) $\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \frac { \mathrm { x } - 3 } { 4 }$
