Well, it might be easier to visualize. Actually, I'll try it both places. So it's this entire distance right over here. Essentially, the distance between the vertical line, the horizontal distance between our vertical line and our outer function, the horizontal distance between our vertical line and our outer function. So if you think about it in terms of x, it's going to be 2 minus whatever the x value is right over here. So the x value right over here is going to be y squared. Remember, we want this as a function of y.
