This is a vertical parabola open upward
The vertex represent the minimum value
The quadratic equation in vertex form is
where
a is a coefficient
(h,k) is the vertex
so
Convert the quadratic equation in vertex form
Factor 2 leading coefficient
Complete the squares
Rewrite as perfect squares
The vertex is the point (1,-4)
Move the constant to the right side
