Are conics functions?

Conic sections are relations, not functions. An equation (like for example x2+y2=100) can be thought of as a criterion or condition that can be used to check any point to see if it is part of the relation. Is all conic sections are functions? If the plane does pass through the vertex, various degenerate conic

Is the edge of a half plane another half plane?

Answers. Half-Plane. A half-plane is a planar region consisting of all points on one side of an infinite straight line, and no points on the other side. If the points on the line are included, then it is called an closed half-plane. Can a plane be divided into two half planes? Each line plotted on
