Decide Whether or Not the Functions Are Inverses of Each $$f ( x ) = 9 x ^ { 2 } + 9 , x \geq 0 ; \quad g ( x ) = \sqrt { \frac { x - 9 } { 9 } } , x \geq 9$$

Multiple Choice

Decide whether or not the functions are inverses of each other.Use the definition of inverses to determine whether f and g are inverses.
