The average value of our function over this interval, over this interval, is equal, the average value of our function is equal to four. And notice, our function actually hits that value at some point in the interval. At some point in the interval, something lower than two, but greater than one, we could maybe call that C. It looks like our function hits that value. And this is actually, this is actually a generally true thing. This is a mean value theorem for integrals, and we'll go into more depth there. But you can see that this kind of does look like its average value. That if you imagine the box, if you multiply this height, this average value times this width, you would have this area right over here, and this area right over here is the same, this area that I'm highlighting in yellow right over here, is the same as the area under the curve.
