The function f is one-to-one. State the domain and the range of f and f^-1. Write the domain and range in set-builder
notation.

f ( x ) : D = \left\{ x \mid x \geq \frac { 1 } { 5 } \right\} , R

is all real numbers;

f ^ { - 1 } ( x ) : D = \left\{ x | x \geq 0 \rangle , R = \left\{ y \mid y \geq \frac { 1 } { 5 } \right\} \right.

f ^ { - 1 } ( x ) : D

is all real numbers,

R = \left\{ y \mid y \geq \frac { 1 } { 5 } \right\}
