Find the domain

Dom (f)

and range

Ran (f)

of the function

f (x) = \frac{2 + x}{x + 4}

.

\begin{aligned} Dom (f) & = (- \infty; - 4) \cup (- 4; \infty), \\ Ran (f) & = (- \infty; 1) \cup (1; \infty) \end{aligned}

\begin{aligned} Dom (f) & = (- \infty; 4) \cup (4; \infty), \\ Ran (f) & = (- \infty; 1) \cup (1; \infty) \end{aligned}

\begin{aligned} Dom (f) & = (- \infty; 2) \cup (2; \infty), \\ Ran (f) & = (- \infty; 4) \cup (4; \infty) \end{aligned}

\begin{aligned} Dom (f) & = (- \infty; 4) \cup (4; \infty), \\ Ran (f) & = (- \infty; 2) \cup (2; \infty) \end{aligned}
