Between zero and three. So one way to think about it, you could apply the formula, but it's very important to think about what does that formula actually mean? And once again, you shouldn't memorize this formula because it actually kind of falls out out of what it actually means. So the average of our function is going to be, it's going to be equal to the definite integral over this interval. So essentially, the area under this curve. So it's going to be the definite integral from zero to three of f of x, which is x squared plus one, dx. And then we're gonna take this area.
