Answer
a.$\mathbb{R}$
b $[-2,2]$
c. $x$-intercept $= 0$
d. $y$-intercept $=0$
e. constant for $x\leq-2$
increasing on $(-2,2)$
constant for $x\geq2$
f. $f(-9)=-2$ and $f(14)=2$
Work Step by Step
As we can see from the graph,
a. Domain=$\mathbb{R}$, all real number
b. Range=$[-2,2]$
c. $x$-intercept $= 0$
d. $y$-intercept $= 0$
e. $f(x)$ is constant of $x\leq-2$
$f(x)$ is increasing on $(-2,2)$
$f(x)$ is constant for $x\geq2$
f. $f(-9)=-2$ and $f(14)=2$
