If $A = \{a, b, c, d\}$ and the function $f = \{(a, b), (b, d), (c, a), (d, c)\}$, write $f^{-1}$. |
$f^{-1} = \{(a, b), (b, d), (c, a), (d, c)\}$ $f^{-1} = \{(b, a), (d, b), (a, c), (c, d)\}$ $f^{-1} = \{(a, c), (b, a), (c, d), (d, b)\}$ $f^{-1} = \{(b, d), (d, a), (a, c), (c, b)\}$ |
$f^{-1} = \{(b, a), (d, b), (a, c), (c, d)\}$ |
The correct answer is Option (2) → $f^{-1} = \{(b, a), (d, b), (a, c), (c, d)\}$ ## Given that, $A = \{a, b, c, d\}$ and $f = \{(a, b), (b, d), (c, a), (d, c)\}$ $∴f^{-1} = \{(b, a), (d, b), (a, c), (c, d)\}$ |
