Can you please explain how this is the answer? I don't understand the notes my teacher provided 

Which statement about the functions f and g is correct?
2 x
f (x) = -2x + 2
g (x) =
2
Of (9(x)) = r and g (f (x)) = , so f and g are inverse functions.
Of (g (x)) = 1 and g (f (x)) = x, so ƒ and g are not inverse functions.
O f (g (x))
= x and g (f (x))=x, so f and g are not inverse functions.
f (g(x)) = x and g (f (x)) = x, so f and g are inverse functions.
