Answer

(a) $(\frac{1}{3},0),(\frac{5}{2},0),(0,\frac{1}{2})$. (b) domain $[-3,3]$ and range $[-1,2]$ (c) increasing $(2,3)$, decreasing $(-1,1)$, constant $(-3,-1),(1,2)$ (d) neither

Work Step by Step

(a) Based on the graph, we can find the intercept(s) $(\frac{1}{3},0),(\frac{5}{2},0),(0,\frac{1}{2})$. (b) We can find the domain $[-3,3]$ and range $[-1,2]$ (c) The intervals on which the function is increasing $(2,3)$, decreasing $(-1,1)$, constant $(-3,-1),(1,2)$ (d) We can identify that the function is neither even or odd.
