Answer
(a) domain $(-\infty,\infty)$ and range $[-4,\infty)$.
(b) $(-3,-4)$.
(c) $x=-3$.
(d) $5$.
(e) $-5, -1$.
Work Step by Step
(a) Based on the given graph, we can find the domain as $(-\infty,\infty)$ and range as $[-4,\infty)$.
(b) The coordinates of the vertex can be found as $(-3,-4)$.
(c) The equation of the axis can be identified as $x=-3$.
(d) The y-intercept can be found as $f(0)=5$.
(e) The x-intercepts can be found as $x=-5, -1$.
