Answer:
[tex]y\geq -6[/tex]
Step-by-step explanation:
we know that
The graph of the figure represent a vertical parabola open upward
The vertex represent a minimum
The vertex of the quadratic equation is the point (h,k)
The range of the quadratic equation is the interval for y [k,∞)
[tex]y\geq k[/tex]
Looking at the graph
The vertex is the point (0,-6)
therefore
The range is the interval [-6,∞)
[tex]y\geq -6[/tex]
