Finally, when x is just less than negative 3, remember when I write this, I don't mean for all x's larger than negative 3 or all x's smaller than negative 3. There's actually no notation that would say just as we just approach 3, in this case, from the left. What happens if we just go to minus 3.11 or 3.01? This term right here is going to be positive. If we take minus 3.1 to the fourth, that's going to be larger than positive 81. The sign will become positive. It will be larger than 81, so this will become negative.
