## What is directrix parabola?

A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola, and the line is called the directrix . The directrix is perpendicular to the axis of symmetry of a parabola and does not touch the parabola.

## What is a simple definition of a parabola?

Definition of parabola 1 : a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line : the intersection of a right circular cone with a plane parallel to an element of the cone. 2 : something bowl-shaped (such as an antenna or microphone reflector)

What are the four types of parabola?

Four Common Forms of a Parabola:

Form: y2 = 4ax x2 = – 4ay
Vertex: (0, 0) (0, 0)
Focus: (a, 0) (0, -a)
Equation of the directrix: x = – a y = a
Equation of the axis: y = 0 x = 0

What is equation of Directrix?

The directrix of a parabola can be found, by knowing the axis of the parabola, and the vertex of the parabola. For an equation of the parabola in standard form y2 = 4ax, with focus at (a, 0), axis as the x-axis, the equation of the directrix of this parabola is x + a = 0 .

### What is a Directrix of a hyperbola?

Directrix of a hyperbola is a straight line that is used in generating a curve. It can also be defined as the line from which the hyperbola curves away from. This line is perpendicular to the axis of symmetry. The equation of directrix is: x = ± a 2 a 2 + b 2.

### What is half of a parabola called?

The graph of the equation y = √x+ 2 is the “top half” of the. parabola and the graph of the equation y = – √x + 2 gives the “bottom half.” Graphing Parabolas. The graphs of quadratic equations (y = ax2 + bx + c) are called parabolas.

What are the two types of parabolas?

Types of Parabolas. A parabola is the shape of a quadratic function graph. There are two types of parabolas, positive (opening up) or negative (opening down).

What is parabola and types of parabola?

A parabola is a set of all points in a plane that are equidistant from a fixed line and fixed point in the plane. A line through the focus and perpendicular to the diretrix is called the axis of the parabola. The point of intersection of the parabola with its axis is called the vertex of the parabola.
