Find the domain \(\mathrm{Dom}(f)\)
and range \(\mathop{\mathrm{Ran}}(f)\) of
the function \(f(x) = \frac{2+x}
{x+4}\).
\begin{align*}
\mathrm{Dom}(f) &= (-\infty ;-4)\cup (-4;\infty ),\\
\mathop{\mathrm{Ran}}(f) &= (-\infty ;1)\cup (1;\infty )
\end{align*}
\begin{align*}
\mathrm{Dom}(f) &= (-\infty ;4)\cup (4;\infty ), \\
\mathop{\mathrm{Ran}}(f) &= (-\infty ;1)\cup (1;\infty )
\end{align*}
\begin{align*}
\mathrm{Dom}(f) &= (-\infty ;2)\cup (2;\infty ),\\
\mathop{\mathrm{Ran}}(f) &= (-\infty ;4)\cup (4;\infty )
\end{align*}
\begin{align*}
\mathrm{Dom}(f) &= (-\infty ;4)\cup (4;\infty ), \\
\mathop{\mathrm{Ran}}(f) &= (-\infty ;2)\cup (2;\infty )
\end{align*}
