Answer:
4
Step-by-step explanation:
The average rate of change of any function f(x)within a interval [a,b] is given by the formula.
Avg rate of change=[tex]\frac{f(b)-f(a)}{b-a}[/tex]
In our problem , the limits are 0 and 2 , that means ,
b=2
a=0
Also we are given values of function at 2 and 0.
f(2)=8
f(0)=0
Let us put these values in our formula
Avg rate of change=[tex]\frac{8-0}{2-0}[/tex]
Avg rate of change=[tex]\frac{8}{2}[/tex]
Avg rate of change=[tex]4[/tex]
Answer = 4
