That's exactly what we have over here. This is the graph of y is equal to f of x. But what I want to do is I want to approximate the graph of y is equal to, so my goal is to graph y is equal to f of x, f of x plus g of x, plus g of x, plus g of x. 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.
