For this case we have:
The equation in vertex form of the parabola is given by:

The vertex is (h, k) and is given by the highest or lowest point of the parabola, in this case it is observed that it is

Thus, the equation is given by:

We look for the value of a, substituting a point of the parabola in the equation in the form of vertex, we will take the point

Substituting we have:



Thus, the equation of the parabola is given by:

Answer:
