Answer:
Average Rate of Change= 12
Explanation:
We know that the average rate of change formula is

so if we input x=2, y=(2)^2. y = 4. Next we input x=10 y=(10)^2 y=100
2,4 is the first coordinate
10,100 is the second coordinate
put these numbers in the equation
=

96/8 = 12
you average rate of change is 12
