Multiple Choice

Determine whether the function has an inverse function.If it does, find the inverse function. f(x) = x² + 5

A) $f ^ { - 1 } ( x ) = \sqrt { x } + 5 , x \geq 0$
B) $f ^ { - 1 } ( x ) = \sqrt { x - 5 }$
C) $f ^ { - 1 } ( x ) = \sqrt { x } - 5$
D) $f ^ { - 1 } ( x ) = \sqrt { x + 5 } , x \geq - 5$
E) No inverse function exists.
