Put into standard form and then read the vertex and symmetry axis from that form of the equation.

y=a%28x-h%29%5E2%2Bk
Vertex is (h,k) and symmetry axis is x=h.

Find the vertex and axis of symmetry of the graph of the function.
f(x) = -3x^2 - 6x - 2
a. (-1, 1) ; x = -1
b. (2, -26) ; x = 2
c. (1, -11) ; x = 1
d. (-2, -8) ; x = -2
The x-coordinate of the vertex or axis of symmetry occurs at:  

The y-coordinate of the vertex occurs at: 

Vertex: highlight_green%28matrix%281%2C3%2C+%22%28-+1%22%2C+%22%2C%22%2C+%221%29%22%29%29
