Explanation:

When a plane intersects only one nappe of a double - napped cone and is parallel to a generating line, the conic section formed is a parabola. A circle is formed when the plane is perpendicular to the axis of the cone. An ellipse is formed when the plane intersects one nappe and is not parallel to a generating line and not perpendicular to the axis. A hyperbola is formed when the plane intersects both nappes of the cone.

Answer:

parabola
