I will show you how to do this in general, and then you can do this problem and any one you encounter like it in the future:
Given:
\ =\ ax^2\ +\ bx\ +\ c)
The 
-coordinate of the vertex is:
The 
-coordinate of the vertex is then:
\ =\ a(x_v)^2\ +\ b(x_v)\ +\ c)
And the equation of the axis of symmetry is:
Bonus fact: The -intercepts, if they exist, are located at:
)
and the -intercept is located at )

My calculator said it, I believe it, that settles it
