directrix
focus
It is called the directrix.
All of the points on a parabola define a parabola. However, the vertex is the point in which the y value is only used for one point on the parabola.
A cubic line is in a cube shape line. and Parabola is a straight line
There are several ways of defining a parabola. Here are some:Given a straight line and a point not on that line, a parabola is the locus of all points that are equidistant from that point (the focus) and the line (directrix).A parabola is the intersection of the surface of a right circular cone and a plane parallel to a generating line of that surface.A parabola is the graph of a quadratic equation.
It's the focus LOcs!!
i think its the vertex.
The line of symmetry located on a parabola is right down the center. A parabola is a U shape. Depending on the direction of the parabola it either has a x axis of symmetry or y axis of symmetry. You should have two equal sides of the parabola.
It is the axis. NOT the directrix which does not even touch the parabola.
it's called the focus
