axis parallel to Ox=>your parabola opens right/left
Vertex form:

vertex on O=>

............passing through (, ) , use it to calculate and

..........1)

passing through (, )

..........2)

from 1) and 2) we have

=> or

then, if
..........1)

or, if

and your equations are:

.........1
or

.........2
