And so you can immediately see that something interesting happens at x is equal to one. If you were to just substitute x equals one into this expression, you're going to get two over zero. And whenever you get a non-zero thing over zero, that's a good sign that you might be dealing with a vertical asymptote. In fact, we can draw that vertical asymptote right over here at x equals one. But let's think about how that relates to limits. What if we were to explore the limit as x approaches one of f of x is equal to two over x minus one? And we could think about it from the left and from the right.
