Answer:
A
Explanation:
the range is the interval or set of all valid y-values.
we see that 5 points are marked.
each point has an y-value.
and we see that each point has a different y-value.
So, C and D are out.
by going bottom-up we see the y-values of the points :
-6, -5, -2, 3, 5
so, A is the correct answer.
