So given this, given this information, this function definition, what I would like you to do is come up with the absolute maximum value of f. Where f is defined right over here, where f is defined on this closed interval. I encourage you to pause this video and think about it on your own. So the extreme value theorem tells us, look, if we've got some closed interval, I'm going to speak in generalities here, so let's say that's our x-axis. And let's say we have some function that's defined on a closed interval. We have a couple of different scenarios for what that function might look like on that closed interval. So we might hit a maximum point. We might hit a maximum point at the beginning of the interval, something like that.
