Find the vertex and axis of symmetry of the graph of the function.
f(x) = -3x^2 - 6x - 2
-----
Vertex occurs where x = -b/(2a) = 6/(2*-3) = 1
--------
f(1) = -3-6-2 = -11
----------------------
Vertex:: (1,-11)
Axis of symmetry:: x = 1

Find the vertex and axis of symmetry of the graph of the function.
f(x) = -3x^2 - 6x - 2
x-coordinate of vertex, or axis of symmetry: highlight_green%28x+=+-+1%29

y-coordinate of vertex: -+3%28-+1%29%5E2+-+6%28-+1%29+-+2+=+-+3%281%29+%2B+6+-+2+=+-+3+%2B+6+-+2+=+1
