Find the domain

Dom (f)

and range

Ran (f)

of the function

f (x) = \frac{x - 3}{x + 1}

.

\begin{aligned} Dom (f) & = (- \infty; - 1) \cup (- 1; \infty), \\ Ran (f) & = (- \infty; 1) \cup (1; \infty) \end{aligned}

\begin{aligned} Dom (f) & = (- \infty; 1) \cup (1; \infty), \\ Ran (f) & = (- \infty; - 1) \cup (- 1; \infty) \end{aligned}

\begin{aligned} Dom (f) & = (- \infty; 3) \cup (3; \infty), \\ Ran (f) & = (- \infty; - 1) \cup (- 1; \infty) \end{aligned}

\begin{aligned} Dom (f) & = (- \infty; - 3) \cup (- 3; \infty), \\ Ran (f) & = (- \infty; 1) \cup (1; \infty) \end{aligned}
