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. And then when x is equal to b, g of x is about that big, so I have to add that length, which is about, which looks something like that. That actually looks like a little bit too much. Maybe something like that.
