The equation of a vertical parabola into vertex form is equal to
where
(h,k) is the vertex of the parabola
if a> 0 then the parabola open upward (vertex is a minimum)
if a< 0 then the parabola open downward (vertex is a maximum)
In this problem we have
Convert to vertex form
Complete the square
--------> equation in vertex form
The vertex is the point
the parabola open upward (vertex is a minimum)
