How to Find Equation of a Parabola | Sciencing
https://sciencing.com/equation-parabola-8270029.html
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 = ax 2 + bx + c , where a ≠ 0, then congratulations!

Parabola Formula What is Parabola? Parabola is a section of a right circular cone by a plane parallel to a generator of the cone. It is a locus of a point, which moves so that distance from a fixed point is equal to the distance from a fixed-line. Equation of Parabola. y 2 = x is the simplest equation of a parabola when the directrix is parallel to the y-axis.

Now, we take a point P(x, y) on the parabola such that, PF = PB … (1) … where PB is perpendicular to l. The coordinates of the point B are (- a, y). Also, by the distance formula, we know that. PF = √ {(x – a) 2 + y 2} Also, PB = √ (x + a) 2. Since, PF = PB [from eq. (1)], we get √ {(x – a) 2 + y 2} = √ (x + a) 2
