Consider the function \(f\colon y =\mathop{\mathrm{tg}}\nolimits x\) with
domain restricted to the interval \(\mathop{\mathrm{Dom}}(f) = \left ( \frac{\pi }{2}; \frac{3\pi }
{2}\right )\).
In the following list identify the function with domain
\((0;\pi )\).
\(f\left (x + \frac{\pi } {2}\right )\)
\(\left ( \frac{\pi }{2}\right )\cdot f(x)\)
\(f\left (x - \frac{\pi } {2}\right )\)
\(f(x) + \frac{\pi } {2}\)
\(f(x) - \frac{\pi } {2}\)
