Určte \(D(f)\) a \(H(f)\) funkcie \(f\colon y = \frac{2+x} {x+4}\).
\begin{align*} D(f) &= (-\infty ;-4)\cup (-4;\infty ), \\ H(f) &= (-\infty ;1)\cup (1;\infty )\end{align*}
\begin{align*} D(f) &= (-\infty ;4)\cup (4;\infty ), \\ H(f) &= (-\infty ;1)\cup (1;\infty )\end{align*}
\begin{align*} D(f) &= (-\infty ;2)\cup (2;\infty ),\\ H(f) &= (-\infty ;4)\cup (4;\infty )\end{align*}
\begin{align*} D(f) &= (-\infty ;4)\cup (4;\infty ), \\ H(f) &= (-\infty ;2)\cup (2;\infty )\end{align*}
