And if this little, this little, I guess you could say, leap that I just made right over here doesn't make sense to you, think about it visually. Think about it visually. So if this is my y-axis, and this is my x-axis, g of x looked something like this. The g of x, the g of x, let me draw it, g of x looked something, something like this. And it had a gap at negative one. So it had a gap right over there. While f of x, f of x would have the same graph, except it wouldn't have, it wouldn't have the gap.
