Answer
See answers below.
Work Step by Step
Based on the given graph, we have:
a. the domain of $f$ is $(-4,\infty)$
b. the range of $f$ is $(-\infty,0]$
c. interval(s) where $f$ is constant: $(-4,-2)$
d. interval(s) where $f$ is decreasing: $(0,\infty)$
e. interval(s) where $f$ is increasing: $(-2,0)$
f. the number at which $f$ has a relative maximum: $x=0$
g. the relative maximum of $f$: $f(0)=0$
h. $f(-3) + f(3)=-2-3=-5$
