What is the vertex of a parabola?

Back

The vertex is the highest or lowest point on the parabola, depending on its orientation. It is the point where the parabola changes direction.

What is the focus of a parabola?

Back

The focus is a fixed point located inside the parabola, which is used in the definition of a parabola. It is located along the axis of symmetry.

What is the directrix of a parabola?

Back

The directrix is a fixed line that is perpendicular to the axis of symmetry and is used in the definition of a parabola. It is located outside the parabola.
