## Algebra and Trigonometry 10th Edition

$D=[-1,\infty);R=(-\infty,7]$ a) 4; b) 3; c) 6; d) 0.
First we determine the domain $D$ and the range $R$ of the function: $D=[-1,\infty)$ $R=(-\infty,7]$ From the graph we determine the function's values in the specified values of $x$: a) $f(-1)=4$ b) $f(0)=3$ c) $f(1)=6$ d) $f(3)=0$
