How to Graph a Hyperbola - dummies
For instance, a hyperbola has two vertices. There are two different equations — one for horizontal and one for vertical hyperbolas: A horizontal hyperbola has vertices at ( h ± a, v ). A vertical hyperbola has vertices at ( h, v ± a ). The vertices for the above example are at (–1, 3 ± 4), or (–1, 7) and (–1, –1).
