You can put this solution on YOUR website! Find the vertex and the line symmetry and how will it look graphed.
F(x)=1/2(x+9)^2+7
-----------------------------------
--------------------------------
Rearrange the equation to get:
(1/2)(x+9)^2 = y-7
--------------
Vertex occurs at (-9,7)
Axis of symmetry x= -9
