So for any given x, it's going to be f of x, so that's the f of x, and I'm going to add the g of x to it. So what would that look like? So that's going to look like, let's see, at when x is zero, g of x looks like it's about that length right there. I'm obviously approximating it, so I'm going to have to add that length right over here, so it'd probably be right around there. At x equals a, it's a little bit more, but now my f of x curve has gone more, has increased, but if I take that same distance above it, if I add the g of x there, it gets me right about there. Once again, I'm just eyeballing it, trying to get an approximation. Give you an intuition, actually, for what f of x plus g of x is.
