What is the average rate of change of the function over the interval x = 0 to x = 8? f(x)=2x−13x+5 enter your answer, as a fraction, in the box.

To find the average rate of change, use the following formula:



a and b represent the values of the interval:



Simplify the original equation by combining like terms:




Plug the interval values into the f(x) equation:




Plug in these values into the average rate of change formula:



The average rate of change over this interval is -11.
