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. So limit from the left. And why do I say the left? Well, if you think about this on a coordinate plane, these are the x values that are to the left of three but we're getting closer and closer and closer.
