All right, now, this would be the graph of just x squared, but it's not x squared when x is equal to 2. So once again, when x is equal to 2, we should have a little bit of a discontinuity here. So I'll draw a gap right over there, because when x equals 2, the function is equal to 1. When x is equal to 2, so let's say that, and I'm not doing them on the same scale, but let's say that, so this, on the graph of f of x is equal to x squared, this would be 4, this would be 2, this would be 1, this would be 3. So when x is equal to 2, our function is equal to 1. So when x is equal to 2, our function is equal to 1. So this is a bit of a bizarre function, but we can define it this way.
