Which function, g or h, is the inverse function of function f?
A. The function h is the inverse because h and f intersect at multiple points.
B. The function h is the inverse because for every point left parenthesis a comma b right parenthesis on the graph of f, there is a corresponding point left parenthesis b comma a right parenthesis on the graph of h.
C. The function g is the inverse because for every point left-parenthesis x comma y right-parenthesis on the graph of f, there is a corresponding point left-parenthesis y comma x right-parenthesis on the graph of g.
D. The function g is the inverse because g and f intersect at one, and only one, point.
