Consider the function \(f(x) =\mathop{\mathrm{cotg}}\nolimits x\) with domain restricted to the interval \(\mathop{\mathrm{Dom}}(f) = (0;\pi )\). In the following list identify the function with domain \(\left (0; \frac{\pi } {3}\right )\).
\(f(3\cdot x)\)
\(f(x - 3)\)
\(f(x + 3)\)
\(f\left (\frac{x} {3} \right )\)
\(3\cdot f(x)\)
