Question

Identify the range of the function shown in the graph

Answer 1

The range is the possible values of  the function 
AS you see on the graph it ranges from 0 to 8

Its choice B.

Answer 2

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 $-6\le x\le 6$ (if you draw verical lines, they will intersect the graph only for $-6\le x\le 6$);
• the range is $0\le y \le 8$ (if you draw horizontal lines, they will intersect the graph only for $0\le y\le 8$).

Answer: correct choice is B.
