-$$f ( x ) = 5 x + 3$$
A) $f ^ { - 1 } ( x ) = \frac { x - 3 } { 5 }$
B) Not a one-to-one function
C) $f ^ { - 1 } ( x ) = \frac { x } { 5 } - 3$
D) $f ^ { - 1 } ( x ) = \frac { x + 3 } { 5 }$

To find the inverse, swap $x$ and $y$, then solve for $y$: $x = 5y + 3$, leading to $y = \frac{x - 3}{5}$, which matches choice A.
