In some designs of eyeglasses, the surface is “aspheric,” meaning that the contour varies slightly from spherical. An aspheric lens is often used to correct for spherical aberration–a distortion due to increased refraction of light rays when they strike the lens near its edge. Aspheric lenses are often designed with hyperbolic cross sections.
Write an equation of the cross section of the hyperbolic lens shown if the center is (0, 0), one vertex is
