Answer:
the average rate of change would 2
Explanation:
to find the ARC you need two points (3,6) and (5,10) and to know how to find the ARC. it is quite easy if you use the equation (y2 - y1)/(x2 - x1). now you know what the equation to solve for ARC so you can place the points in:
(y2 - y1)/(x2 - x1)
(10 - 6) / (5 - 3)
(4) / (2) = 2
so the ARC would equal 2
