Answer
$D=(-2,2],R=[-1,8]$
a) -1; b) 0; c) -1; d) 8
Work Step by Step
First we determine the domain $D$ and the range $R$ of the function:
$D=(-2,2]$ (the point $(-2,8)$ does not belong to the graph, so $-2\not \in D$)
$R=[-1,8]$
From the graph we determine the function's values:
a) $f(-1)=-1$
b) $f(0)=0$
c) $f(1)=-1$
d) $f(2)=8$
