Answer:

Step-by-step explanation:
we know that
The equation of a vertical parabola into vertex form is equal to

where (h,k) is the vertex of the parabola
The axis of symmetry is equal to

In this problem the parabola open upward
so
the coefficient a is positive
The coordinates of the vertex will be
(the y-coordinate is negative)
so
the equation will be of the form
