If you just said x is equal to square root of x, when does x equal square root of x? I mean, you could square both sides of this. You could say, when does x squared equal x? You could, well, we could keep it there. You could kind of solve this. There's multiple ways you could do it, but you could solve this kind of just thinking about it. If x is equal to 0, x squared is equal to x, and you see that on the graph right over here.
