The reason why I set up two tables, I didn't have to do two tables, I could have done it all in one table but hopefully this will make it a little bit more intuitive what I'm trying to do is on this left table, I'm gonna, let's try out x values that get closer and closer to three from the left, from values that are less than three. So for example, we could go to 2.9 and figure out what the expression equals when x is 2.9. But then we could try to get even a little bit closer than that. We could go to 2.99. And then we could go even closer than that. We could go to 2.999. And so one way to think about it here is as we try to figure out what this expression equals as we get closer and closer to three, we're trying to approximate the limit from the left.
