## Algebra and Trigonometry 10th Edition

$D=(-2,2],R=[-1,8]$ a) -1; b) 0; c) -1; d) 8
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) $f(2)=8$
