Answer
(a) $(\pm2,0),(0,3)$.
(b) domain $[-4,4]$ and range $[0,3]$
(c) increasing $(-2,0),(2,4)$, decreasing $(-4,-2),(0,2)$.
(d) even.
Work Step by Step
(a) Based on the graph, we can find the intercept(s) $(\pm2,0),(0,3)$.
(b) We can find the domain $[-4,4]$ and range $[0,3]$
(c) The intervals on which the function is increasing $(-2,0),(2,4)$, decreasing $(-4,-2),(0,2)$.
(d) We can identify that the function is even.
