Question 910749: I need to know the vertex, axis of symmetry, roots, domain and the range of the following problem
Y=-x^2+9
I also need to know if it opens up or down and a graph would be greatly appreciated. Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! It's already in vertex form although it's disguised.
The vertex is (,).
The axis of symmetry is .
It opens downwards since the coefficient of the quadratic term is negative.
The domain is all real numbers.
The maximum value occurs at the vertex so the range is (,).
