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*}
