Answer
(a) $(-3,\infty)$.
(b) $x=-\frac{1}{2}$, $y=1$.
(c) See graph.
(d) $(-\infty,5)$.
Work Step by Step
Based on the given piece-wise function, we have:
(a) the domain $(-3,\infty)$.
(b) the x-intercept(s) (let y=0): $x=-\frac{1}{2}$, y-intercept(s) (let x=0): $y=1$.
(c) See graph.
(d) Based on the graph, we can find the range $(-\infty,5)$.
