Find the domain \(\mathrm{Dom}(f)\)
and range \(\mathop{\mathrm{Ran}}(f)\) of
the function \(f(x) = \frac{x-3}
{x+1}\).
\begin{align*}
\mathrm{Dom}(f) &= (-\infty ,-1)\cup (-1,\infty ),\\
\mathop{\mathrm{Ran}}(f) &= (-\infty ,1)\cup (1,\infty )
\end{align*}
\begin{align*}
\mathrm{Dom}(f) &= (-\infty ,1)\cup (1,\infty ),\\
\mathop{\mathrm{Ran}}(f) &= (-\infty ,-1)\cup (-1,\infty )
\end{align*}
\begin{align*}
\mathrm{Dom}(f) &= (-\infty ,3)\cup (3,\infty ),\\
\mathop{\mathrm{Ran}}(f) &= (-\infty ,-1)\cup (-1,\infty )
\end{align*}
\begin{align*}
\mathrm{Dom}(f) &= (-\infty ,-3)\cup (-3,\infty ),\\
\mathop{\mathrm{Ran}}(f) &= (-\infty ,1)\cup (1,\infty )
\end{align*}
