Answer:
2
Explanation:
We are given that
The rate of change between point A and point B is 2.
We have to find the rate of change between point C and point D.
From given graph
The point C=(1,2)
D=(2,4)
Rate of change is given by =
Substitute the values then we get
Rate of change=
Hence, the rate of change between point C and point D =2
