If y=f(x) is the function, then
- the domain of the function are all possible values of variable x;
- the range of the function are all possible values of variable y.
From the graph you can see that
- the domain is [tex]-6\le x\le 6[/tex] (if you draw verical lines, they will intersect the graph only for [tex]-6\le x\le 6[/tex]);
- the range is [tex]0\le y \le 8[/tex] (if you draw horizontal lines, they will intersect the graph only for [tex]0\le y\le 8[/tex]).
Answer: correct choice is B.
