What is a parabola?

Back

A parabola is a U-shaped curve that is defined as the set of all points in a plane that are equidistant from a fixed point (the focus) and a fixed line (the directrix).

What is the vertex of a parabola?

Back

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

Front

What is the axis of symmetry in a parabola?

Back

The axis of symmetry is a vertical line that divides the parabola into two symmetrical halves. It passes through the vertex.
