That is the rate of change of f at any point x. And so if you wanna find the average value of this over the interval, you would integrate it from our starting point, from negative four to three dx, and then you would divide it by your change in x. So then you would divide it by, you would have it over one over seven. Over one over seven. But then this part right over here is just going to be the same thing as f of three minus f of four. And then this over here, you have a seven in the denominator. So this is really just your change in x.
