On the left-hand side, no matter how close you get to 1, as long as you're not at 1, you're actually at f of x is equal to 1. Over here, from the right-hand side, you get the same thing. So you could say, and we'll get more and more familiar with this idea as we do more examples, that the limit as x, and lim, short for limit, as x approaches 1 of f of x is equal to, as we get closer, we can get unbelievably, we can get infinitely close to 1, as long as we're not at 1, and our function is going to be equal to 1. It's getting closer and closer to 1. It's actually at 1 the entire time. So in this case, we could say the limit as x approaches 1 of f of x is 1. So once again, it has very fancy notation, but it's just saying, look, what is the function approaching as x gets closer and closer to 1?
