Answer:
B- 2
Step-by-step explanation:
Well since the answer got deleted. I'm just going to copy and paste my comment from earlier.
you simply plug in the x's in. Since someone already answers, I'll have to answer in the comment.s (2)^2-2+4 = 6 and (4)^2-4+4= 8. So the average rate of change is 2. B. ;) hope that helps
