- Parabola - Wikipedia
The parabola is a member of the family of conic sections 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
- Parabola - Formula, Graphing, Examples | Parabola Equation
A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point and a fixed line Its general equation is of the form y^2 = 4ax (if it opens left right) or of the form x^2 = 4ay (if it opens up down)

Definition 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 | Definition, Origin, Equation, Applications . . .
The parabola is an open curve that is a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone
- What are parabolas, their equations, their rules? | Purplemath
What is a parabola? A parabola is a particular type of geometrical curve which, algebraically, corresponds to a quadratic equation In geometrical terms, the parabola corresponds to the edge of slice of an inverted cone; this slice is what is called the conic "section"
- Parabolas - California State University, Northridge
We say that the first parabola opens upwards (is a U shape) and the second parabola opens downwards (is an upside down U shape) In order to graph a parabola we need to find its intercepts, vertex, and which way it opens Given y = ax 2 + bx + c , we have to go through the following steps to find the points and shape of any parabola:

Previously, we learned about a parabola’s vertex and axis of symmetry Now we extend the discussion to include other key features of the parabola (Figure 2 4 3) Notice that the axis of symmetry passes through the focus and vertex and is perpendicular to the directrix The vertex is the midpoint between the directrix and the focus
