Answer
(a) domain: $[-3,3]$, range: $[-2,2]$
(b) increasing: $(-2,-1)$ and $(1,2)$
decreasing: $(-3,-2)$, $(-1,1)$ and $(2,3)$
Work Step by Step
(a) The domain consists of the values that $x$ takes on and the range consists of values that $y$ takes on. We see from the graph that the domain is: $[-3, 3]$ and the range is: $[-2, 2]$.
(b) We see from the graph that the function is increasing for $x$ intervals $(-2,-1)$ and $(1,2)$ and decreasing for $x$ intervals $(-3,-2)$, $(-1,1)$ and $(2,3)$.
