WebA "normal" or "unshifted" hyperbola: x^2/a^2 - y^2/b^2 = 1. A "shifted" hyperbola: (x-h)^2/a^2 - (y-k)^2/b^2 = 1. where h and k specify the amount of horizontal and vertical shift respectively. In Sal's examples so far, h and k have effectively been zero, so the asymptotes have gone through the origin. Comment.
