>> Let's construct a graph. Let's see, we had--these are our vertices. Our A value you see was 1 and then from the center we identified the B distance of 3 so we'll go up 1, 2, 3 and down 1, 2, 3 and this allows us to make that little reference rectangle, it's right here, that's the reference rectangle; and now our asymptotes are these and our graph snuggles up to the asymptotes at the extremes of the coordinate plane so it looks like this. By the way the reason that the branches are curved so gently is because the foci [assumed spelling] are so far away from the vertices; and the farther they are away the more gentle this curve will be.
