Answer
(a) See graph.
(b) $(-\infty,0)U(0,\infty)$, $(-\infty,0)U(0,\infty)$
(c) $x=0$, $y=0$
Work Step by Step
(a) To obtain the graph of $R(x)=\frac{3}{x}$ from $y=\frac{1}{x}$, stretch the curve vertically by a factor of 3. See graph.
(b) Based on the graph, we can find the domain as $(-\infty,0)U(0,\infty)$ and range as $(-\infty,0)U(0,\infty)$
(c) We can identify the vertical asymptote $x=0$, horizontal asymptote $y=0$, or oblique asymptote $none$.
