Multiple Choice

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

A) $f ^ { - 1 } ( x ) = x ^ { 2 } - 5 , x \geq 0$
B) $f ^ { - 1 } ( x ) = x ^ { 2 } - 25 , x \geq 0$
C) $f ^ { - 1 } ( x ) = ( x - 25 ) ^ { 2 }$
D) $f ^ { - 1 } ( x ) = ( x - 5 ) ^ { 2 }$
E) The function does not have an inverse.
