a. $(-\infty,\infty)$ b. $(-\infty,3]$ c. $x=-2, 3$ d. $y=3$ e. $(-\infty,3)$, $(0,\infty)$ f. $f(-2)=0, f(6)=-3$
Using the figure given in the exercise, we have: a. the function’s domain as $(-\infty,\infty)$ b. the function’s range as $(-\infty,3]$ c. the x-intercepts as $x=-2, 3$ d. the y-intercept as $y=3$ e. intervals on which the function is increasing as $(-\infty,3)$, decreasing as $(0,\infty)$ f. $f(-2)=0, f(6)=-3$
