A hyperbola with a center at (0, 0) can be defined as x²/a² − y²/b² = ±1.<span> </span>The statement "<span>The symmetry of a hyperbola with a center at (h, k) only occurs at y = k" </span>is false, because a hyperbola have many different orientations. It doesn't have to be symmetric about the lines y = k or x = h.
