If R is a relation from set A to set B, then inverse relation of R to be denoted by R-1, is a relation from set B to set A.
Symbolically R-1 = {(b, a): (a, b) ∈ R for all a ∈ A and b ∈ B}.
Calculation:
R = {(1, 2), (3, 4), (2, 4)} to find R-1 reverse the sequence (a, b) to (b, a).
R-1 = {(2, 1), (4, 3), (4, 2)}
Hence, option 3 is the correct answer.
