Answer
Domain = $[-2,4].$
Range = $[0,4]$
a. 0
b. 4
c. 3
d. $x=-1.5, x=1.5$, and $x=2.5$
Work Step by Step
Endpoints of the curve are included,
Domain = $[-2,4].$
The function values range between 0 and 4.
Range = $[0,4]$
a.
$(-2,0)$ is on the graph, so $f(-2)=0$
b.
$(0,4)$ is on the graph, so $f(0)=4$
c.
$(1/2,3)$ is on the graph, so $f(1/2)=3$
d.
Drawing a horizontal line $y=1$,
the intercections with the graph are at
$x=-1.5, x=1.5$, and $x=2.5$
