In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped. It fits several superficially different mathematical descriptions, which can all be proved to define exactly the same curves. One description of a parabola involves a point (the focus) and a line (the directrix).
A parabola is the locus of a point that is equidistant from a fixed point called the focus (F), and the fixed-line is called the Directrix (x + a = 0). Let us consider a point P(x, y) on the parabola, and using the formula PF = PM, we can find the equation of the parabola.
A parabola is a curve where any point is at an equal distance from: a fixed point (the focus), and; a fixed straight line (the directrix)
Parabola. A parabola is the characteristic U-shaped curve of a quadratic equation. A parabola can be used to model many real-world phenomena. For example, when you shoot a basketball, the path of the ball creates a parabola. Below are two parabola graph examples, one in which the parabola opens upwards and one in which it opens downwards:
A parabola is a U-shaped curve that is also found in the path of water in a fountain or the shape of satellite dishes. Mathematically, it is the graph of a quadratic function in two variables, y = ax 2 + bx + c, that can be defined as the set of all points that are equidistant from a fixed point, called the focus , and a fixed line, called the ...

Parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. As a plane curve, it may be defined as the path of a point moving so that its distance from a fixed line is equal to its distance from a fixed point.

A parabola is defined as the locus (or collection) of points equidistant from a given point (the focus) and a given line (the directrix). Another important point is the vertex or turning point of the parabola.
