1. If \(\{(a, 8), (6, b)\}\) represents an identity function, then the value of \(a\) and \(b\) are respectively.
2. Let \(A = \{1, 2, 3, 4\}\) and \(B = \{4, 8, 9, 10\}\). A function \(f : A \rightarrow B\) given by \(f = \{(1, 4), (2, 8), (3, 9), (4, 10)\}\) is a:
3. If \(f : A \rightarrow B\) is a bijective function and if \(n(B) = 7\), then \((n(A))\) is equal to:
