How do you find the equation of a parabolic graph?
We can use the vertex form to find a parabola’s equation. The idea is to use the coordinates of its vertex (maximum point, or minimum point) to write its equation in the form y=a(x−h)2+k (assuming we can read the coordinates (h,k) from the graph) and then to find the value of the coefficient a.

|---|---|
| (y – k)2 = -4a(x – h) | Vertex (h, k) Parabola opens to the Left side Focus: (h – a, k) Directrix: x = h + a Axis: y = k |
| (x – h)2 = 4a(y – k) | Vertex: (h, k) Parabola opens to the upward Focus: (h, k + a) Directrix: y = k – a Axis: x = h |
What are parabolas used for?
Parabolas are frequently used in physics and engineering for things such as the design of automobile headlight reflectors and the paths of ballistic missiles. Parabolas are frequently encountered as graphs of quadratic functions, including the very common equation y=x2 y = x 2 .
What is an example of parabola?
Parabolas can, in fact, be seen everywhere, in nature as well as manmade items. Consider a fountain. The water shot into the air by the fountain falls back in a parabolic path. A ball thrown into the air also follows a parabolic path.
