In short, use


(f(2) -f(1) )/(2 - 1)

Explanation:

To explain, substitute 1 and 2 for f(x) then divide the difference of the two answers by the difference of the two x coordinates above to find the average rate of change

Answer:

Step One: Evaluate the Function for A and B

f(1) = -6

f(2) = -1.5

Step Two: Use the Average Rate of Change Formula

f(b) - f(a) / b - a

-1.5 - -6 / 2 - 1

4.5 / 1

4.5

The average rate of change is equal to 4.5
