Remember that the average rate of change of a function over an interval is the slope of the straight line connecting the end points of the interval. To find those slopes, we are going to use the slope formula:
m= (y_(2)-y_(1))/(x_2-x_1)

Rate of change of
a:
From the graph we can infer that the end points are (0,1) and (2,4). So lets use our slope formula to find the rate of change of
a:

m= (y_(2)-y_(1))/(x_2-x_1)

m= (4-1)/(2-0)

m= (3)/(2)

m=1.5
The average rate of change of the function
a over the interval [0,2] is 1.5

Rate of change of
b:
Here the end points are (0,0) and (2,2)

m= (2-0)/(2-0)

m= (2)/(2)

m=1
The average rate of change of the function
b over the interval [0,2] is 1

Rate of change of
c:
Here the end points are (0,-1) and (2,0)

m= (0-(-1))/(2-0)

m= (1)/(2)

m=0.5
The average rate of change of the function
c over the interval [0,2] is 0.5

Rate of change of
d:
Here the end points are (0,0.5) and (2,2.5)

m= (2.5-0.5)/(2-0)

m= (2)/(2)

m=1
The average rate of change of the function
d over the interval [0,2] is 1

We can conclude that the function that has the greatest rate of change over the interval [0, 2] is the function a.
