Each of those points gives you a specific equation, so you could have two of them.

will be our best form to start with (my convenience only).

Point (-2, 6):

and since the point is also the vertex,



.

That point being vertex lets us find , so now we only have one unknown variable in the equation other than the general (x, y) variables.

The other given point is (0, -2):






Equation for the parabola is

given:
vertex = (,) and
Step 1:
The standard equation of parabola when the vertex is along intercept is given by:
where vertex:(,) = (,)
and
Step 2:
Putting values of , and in the standard equation and simplifying you get:






is the required equation of parabola.This is the answer.
