a. $(-\infty,\infty)$ b. $[-2,2]$ c. $x=0$ d. $y=0$ e. $(-2,2)$, none f. $f(-9)=-2, f(14)=2$

Work Step by Step

Using the figure given in the exercise, we have: a. the function’s domain as $(-\infty,\infty)$ b. the function’s range as $[-2,2]$ c. the x-intercepts as $x=0$ d. the y-intercept as $y=0$ e. intervals on which the function is increasing as $(-2,2)$, decreasing as none f. $f(-9)=-2, f(14)=2$
