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. I'm just trying to add g of x for a given x. Now let's see, if I'm a little bit, let's say that I'm between a and b, g of x is about that distance right over there. So if I wanted to put that same distance right over here, it gets me right about, it gets me right about there.
