The standard form of hyperbola centered at origin (where ) is
(Transverse axis is horizontal) or
(Transverse axis is vertical).
The equation of hyperbola is .
The - term is positive, so the transverse axis is horizontal and vertices occur at
.
Moreover, the endpoints of the conjugate axis occur at
The hyperbola, graph is
The center of the hyperbola is (0, 0) and its vertices are .
