Answer
(a) $(\pm1,0),(0,2)$.
(b) domain $[-3,3]$ and range $[0,3]$
(c) increasing $(-1,0),(1,3)$, decreasing $(-3,-1),(0,1)$.
(d) even.
Work Step by Step
(a) Based on the graph, we can find the intercept(s) $(\pm1,0),(0,2)$.
(b) We can find the domain $[-3,3]$ and range $[0,3]$
(c) The intervals on which the function is increasing $(-1,0),(1,3)$, decreasing $(-3,-1),(0,1)$.
(d) We can identify that the function is even.
