It is an upside down parabola. Vertex is (600, 50) ?
There are several methods. One of the simplest may be the completed squared form;
where (b,c) is the coordinates of the vertex.
In your case, the formula will be
The negative sign in front of the 'a' indicates that the parabola is 'upside down'
If another point besides the vertex were given, you can work out the value of a by replacing x and y by the respective given coordinates.
