.
The average rate of change of the function f(x) from x= 1 to x= 4 is equal to


    


by the definition.


In other words, you need to calculate the values of the function at x= 4 an at x= 1.


Then take the difference of these values


and then divide the difference by the length of the interval, which (the length) is 4-1 = 3 in your case.
