Answer:
Average rate of change of function is
.
Explanation:
Given Function:

To find: Average rate of change of function over interval of x = 0 to x = 4.
We use the the following formula to find the average rate of change of function f(x) over interval x= a and x = b

here, a = 0 and b = 4
We find value of f(4) ande f(0)by putting x = 4,


So,

Therefore, Average rate of change of function is
.
