Answer
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. $f(-9)=-2, f(14)=2$
