Each "bulb" of the Mandelbrot set is an inverse of one of these figures, because the bulbs are cardioids.
Each "bulb" of the Mandelbrot set is an inverse of one of these figures, because the bulbs are cardioids. Menaechmus found a solution to the problem of doubling the cube by intersecting two of these figures, and Joachim Jungus demonstrated that a catenary was not one of these curves. This shape is the locus of all points equidistant from a focus and a line called a  (*) directrix. This figure is equivalent to an ellipse with one focus at infinity, and it has an eccentricity of one. For ten points, identify this conic section, whose vertical variety is the graph of a quadratic equation, one example of which has equation y equals x-squared.
