Answer
(a) $[-4,\infty)$.
(b) $(0,1)$
(c) See graph
(d) $[-4,0)\cup(0,\infty)$.
(e) No.
Work Step by Step
(a) Based on the given piece-wise function, we can find the domain as $[-4,\infty)$.
(b) We can locate any intercept(s) $(0,1)$
(c) See graph
(d) Based on the graph, we can find the range as $[-4,0)\cup(0,\infty)$.
(e) It is not continuous on its domain (break at $x=0$).
