Multiple Choice

Find the inverse of the function.
- $$f ( x ) = \sqrt { x } - 5 , x \geq 0$$

A) $\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \mathrm { x } + 5 , \mathrm { x } \geq 5$
B) $\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = - ( \mathrm { x } + 5 ) ^ { 2 } , \mathrm { x } \geq 5$
C) $f ^ { - 1 } ( x ) = ( x - 5 ) ^ { 2 }$
D) $f ^ { - 1 } ( x ) = ( x + 5 ) ^ { 2 } , x \geq 5$
