Match the sets of points representing one-to-one functions with the sets of points representing their inverse functions.


Tiles
h = {(1,1), (2,2), (3,3), (4,4), (5,5), (6,6)}

g = {(1,3), (2,6), (3,9), (4,12), (5,15), (6,18)}

f = {(1,2), (2,3), (3,4), (4,5), (5,6), (6,7)}

i = {(1,1), (2,3), (3,5), (4,7), (5,9), (6,11)}


Pairs
h-1 = {(1,1), (2,2), (3,3), (4,4), (5,5), (6,6)}

i -1 = {(1,1), (3,2), (5,3), (7,4), (9,5), (11,6)}

g-1 = {(3,1), (6,2), (9,3), (12,4), (15,5), (18,6)}

f -1 = {(2,1), (3,2), (4,3), (5,4), (6,5), (7,6)}
