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. You can define a function however you like to define it. And so notice, it's just like the graph of x, of f of x is equal to x squared, except when you get to 2, it has this gap, because that's, you don't use the f of x is equal to x squared when x is equal to 2, you use f of x, or I should say g of x, you use g of x is equal to 1. I've been saying f of x, I apologize for that.
