If \(f(x) = \begin{cases} 1 + x & \text{if } 0 \leq x \leq 2 \\ 3 - x & \text{if } 2 < x \leq 3 \end{cases}\) , then \(f[f(x)]\) is
- \(f(f(x)) = \begin{cases} 2 + x & \text{if } 0 \leq x \leq 1 \\ 2 - x & \text{if } 1 < x \leq 2 \\ 4 - x & \text{if } 2 < x \leq 3 \end{cases}\)
- \(f(f(x)) = \begin{cases} 2 + x & \text{if } -1 \leq x \leq 1 \\ 2 - x & \text{if } 1 < x \leq 2 \\ 4 - x & \text{if } 2 < x \leq 3 \end{cases}\)
- \(f[f(x)] = \begin{cases} 2 + x & \text{if } 0 \leq x \leq 1 \\ 2 - x & \text{if } 1 \leq x \leq 2 \\ 4 - x & \text{if } 1 \leq x \leq 3 \\ x & \text{if } 0 \leq x \leq 1 \end{cases}\)
- \(f(f(x)) = \begin{cases} 2 + x & \text{if } -1 \leq x \leq 1 \\ 2 - x & \text{if } 1 < x \leq 2 \\ 4 - x & \text{if } 2 \leq x < 3 \end{cases}\)

If the domain of the function \( f(x) = \frac{1}{\sqrt{3x + 10 - x^2}} + \frac{1}{\sqrt{x + |x|}} \) is \( (a, b) \), then \( (1 + a)^2 + b^2 \) is equal to:
- The domain of the function \[ f(x) = \frac{1}{\sqrt{10 + 3x - x^2}} + \frac{1}{\sqrt{x + |x|}} \] is \( (a, b) \). Then \( (1 + a^2) + b^2 \) is:
- Let \( A = \{1, 2, 3, 4\} \) and \( B = \{1, 4, 9, 16\} \). Then the number of many-one functions \( f: A \to B \) such that \( 1 \in f(A) \) is equal to:
Let \( f(x) = \log x \) and \[ g(x) = \frac{x^4 - 2x^3 + 3x^2 - 2x + 2}{2x^2 - 2x + 1} \] Then the domain of \( f \circ g \) is:
- If the domain of the function \( \log_5 (18x - x^2 - 77) \) is \( (\alpha, \beta) \) and the domain of the function \[ \log_{(x-1)} \left( \frac{2x^2 + 3x - 2}{x^2 - 3x - 4} \right) \] is \( (\gamma, \delta) \), then \( \alpha^2 + \beta^2 + \gamma^2 \) is equal to:
