What are the vertex and the axis of symmetry of the equation?
y=-2x2 + 8x – 18
Overtex: (2,-10)
axis of symmetry: x = 2
Overtex: (2, -10)
axis of symmetry: x = -10
Overtex: (-2,-10)
axis of symmetry: x = -2
Overtex: (-2, 10)
axis of symmetry: y=-2

y = -2x² + 8x - 18
x = -b/2a
x = -8/2(-2)
x = -8/-4
x = 2
y = -2x² + 8x - 18
y = -2(2)² + 8(2) - 18
y = -2(4) + 16 - 18
y = -8 - 2
y = -10
(x, y) = (2, -10)
Vertex: (2, -10)
Axis of Symmetry: x = 2
