In The Ellipse we saw that an ellipse is formed when a plane cuts through a right circular cone. If the plane is parallel to the edge of the cone, an unbounded curve is formed. This curve is a parabola. Parabola You’ve seen parabolas before as the set of all points satisfying a quadratic function. We’ll look at the geometric form of a parabola in this section. It still describes a set of points that satisfy an equation in two variables, but without the need to qualify as a function, it can open left and right as well as up and down. It will be necessary to use another form of its equation to take all of the characteristics of this object into consideration. You’ll learn new terminology for the parts of a parabola just as you did with the ellipse and hyperbola as well. Like the ellipse and hyperbola, the parabola can also be defined by a set of points in the coordinate plane. A parabola is the set of all points ( x , y ) ( 𝑥 , 𝑦 ) in a plane that are the same distance from a fixed l
