If the function \(f: R \rightarrow R\) defined by

f (x) = \{\begin{array}{l} 2 x + 7, \\ x^{2} - 2, \\ 3 x - 2, \end{array} \begin{array}{l} x < - 2 \\ - 2 \leq x < 3 \\ x \geq 3 \end{array}

, then find the values of:

(i) \(f(4)\) \(=\)

(ii) \(f(-2)\) \(=\)

(iii) \(f(4) + 2f(1)\) \(=\)

(iv) \(\frac{f(1) - 3f(4)}{f(-3)}\) \(=\)
