And what are we going to integrate? Well, we're going to integrate the difference between the two functions and really the absolute value of the difference. Remember, we want the sums. We don't wanna have negative area here. We want the sum of the areas of regions r and s. And at some point, you have g of x is above f of x, and at other points, f of x is above g of x. But if we take the absolute value, it doesn't matter which one we're subtracting from the other, we're just getting the absolute value of the difference. So let's take the absolute value of f of x minus g of x dx.
