Let's say that we have g of x is equal to, I could define it this way, we could define it as x squared when x does not equal, I don't know, when x does not equal 2, and let's say that when x equals 2, when x equals 2, it is equal to 1. So once again, a kind of an interesting function that, as you'll see, is not fully continuous. It has a discontinuity. Let me graph it. So this is my y equals f of x axis. This is my x axis right over here. Let me draw x equals 2.
