(y - y1) = A(x - x1)^2

A is the scaling factor

y1 is the y coordinate of a vertex/point on the parabola

x1 is the x coordinate of a vertex/point on the parabola

My two questions are:

1. Can (x,y) be any point on the graph ?

2. If so, then if x - x1 = 0 and y- y1 = 0 (if the difference between the points are 0) then does that mean the point (x,y) is on the parabola?
