If the Function Is One-To-One, Find Its Inverse $$f ( x ) = \sqrt { x + 8 } , x \geq - 8$$

Multiple Choice

If the function is one-to-one, find its inverse. If not, write "not one-to-one."
- $$f ( x ) = \sqrt { x + 8 } , x \geq - 8$$

A) $f ^ { - 1 } ( x ) = \sqrt { x - 8 }$
B) $f ^ { - 1 } ( x ) = x ^ { 2 } - 8 , x \geq 0$
C) not a one-to-one
D) $f ^ { - 1 } ( x ) = ( x + 8 ) ^ { 2 }$
