Or if you were to go from the positive direction, if you were to say 2.1, what's g of 2.1? What's g of 2.01? What's g of 2.001? What is that approaching as we get closer and closer to it? And you can see it visually just by drawing the graph. As g gets closer and closer to 2, and if we were to follow it along the graph, we see that we are approaching 4. Even though that's not where the function is, the function drops down to 1, the limit of g of x as x approaches 2 is equal to 4.
