What are the vertex and the axis of symmetry of the equation?

y = –2x^2 + 8x – 18 (1 point)
vertex: ( 2, –10)
axis of symmetry: x = 2
vertex: (2, –10)
axis of symmetry: x = –10
vertex: (–2, –10)
axis of symmetry: x = –2
vertex: (–2, 10)
axis of symmetry: y = –2

The graph below models the acceleration of a car. Interpret the meaning of the vertex.

The car traveled 10 miles in 60 seconds.
It took the car 20 seconds to accelerate.
It took the car 10 seconds to reach a speed of 60 miles per hour.
It took the car 20 seconds to reach a speed of 60 miles per hour.

y= -2(x^2-4x+9)=-2( x-2)^2 -18+8
(y+10) = -2( x-2)^2
