If the function is one-to-one, list the inverse function by switching coordinates or inputs and outputs.
-f = {(-6, -9), (6, 9), (7, 11), (-7, -11)}
A) f-1 = {(-9, -6), (9, 6), (11, 6), (-11, -7)}
B) f-1 = {(-9, -6), (-6, 6), (11, 7), (-11, -7)}
C) f-1 = {(-9, -6), (9, 6), (11, 7), (-11, -7)}
D) not one-to-one
