Question

If A = {a, b, c, d} and the function f = {(a, b), (b, d), (c, a), (d, c)}, write f^-1.

✓

Answer

We are given that, f = {(a, b), (b, d), (c, a), (d, c)}
An inverse relation is the set of ordered pairs obtained by interchanging the first and second elements of each pair in the original relation.
$\therefore$ f^-1 = {(b, a), (d, b), (a, c), (c, d)}
