We want to determine the value of f(3) that will lead to an average rate of change of 19 over the interval [3, 5].
The average rate of change of f(x) over the interval [a,b]:

If the average rate of change over the interval [3, 5] is 19, then;

From the to table f(5)=13






A.step 1 because it should be x^2 not 2x
First one is 3/8>1/3
Second one is B
Third one is C
Fourth one is B
