Parabola - General Equations, Properties and Practice ...
Standard Equation of Parabola. The simplest equation of a parabola is y 2 = x when the directrix is parallel to the y-axis. In general, if the directrix is parallel to the y-axis in the standard equation of a parabola is given as: y2 = 4ax.

How to Find Equation of a Parabola | Sciencing
The easiest way to find the equation of a parabola is by using your knowledge of a special point, called the vertex, which is located on the parabola itself. Recognizing a Parabola Formula If you see a quadratic equation in two variables, of the form y = ax2 + bx + c , where a ≠ 0, then congratulations! You've found a parabola.

Algebra - Parabolas
The most general form of a quadratic function is, f (x) = ax2 +bx +c f ( x) = a x 2 + b x + c. The graphs of quadratic functions are called parabolas. Here are some examples of parabolas. All parabolas are vaguely “U” shaped and they will have a highest or lowest point that is called the vertex.

Parabola - Wikipedia
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).The focus does not lie on the directrix. The parabola is the locus of points in ...

How to Put Equations of Parabolas in Standard Form - dummies
Write the equation of the parabola x 2 – 16x – 4y + 52 = 0 in standard form to determine its vertex and in which direction it opens. ( x – 8) 2 = 4(1)( y + 3); vertex: (8, –3); opens upward. First rewrite the equation to isolate the x -terms: Leave the two terms with x ’s on the left, and get the other two terms on the right by adding 4y and –52 to both sides.
