Focus of a Parabola The more difficult definition of a parabola is a collection of points where the distance to the focus is equal to the distance to a fixed straight line underneath the parabola (the directrix). The focus is a point on the axis of symmetry, but it is not on the actua...
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)
An example of a parabola could be y=x^2+1. What is a parabola in simple terms? A parabola is a curve in which every point on the curve is equidistant from a point called a focus and a straight line called a directrix. It is a U-shaped curve that appears often in mathematics. It...
If we sketch lines tangent to the parabola at the endpoints of the focal diameter, these lines intersect on the axis of symmetry.How To: Given a standard form equation for a parabola centered at (0, 0), sketch the graph. Determine which of the standard forms applies to the given ...
A parabola is a graph of a quadratic function. It looks like the letter "U" when graphed on a Cartesian plane (an X,Y axis). The quadratic function is ax^2+bx+c = 0, where a, b, and c are numbers called coefficients. The solution for any quadratic equation or parabola can be ...

Students learn how to apply the endpoint math formula -- a derivation of the midpoint formula -- during a unit on graphing in the coordinate plane, which is typically taught in an algebra course but sometimes covered in a geometry course. To use the endpoint math formula, you must already...
How to Graph a Parabola in Word. A parabola is a curved line with particular characteristics. Any point on the curve is the same distance from a fixed point and a fixed straight line. The result looks like half of an ellipse or the arc formed when an obj
