Alright...apparently I am still not getting this! Find the vertex? If I can find the vertex I know I can get the rest. Or if I can get help breaking it down, I may also be able to get it. f(x)=-x^2+6x+6

mertsj · Answer

The x coordinate of the vertex is -b/2a

mertsj · Answer

Find that and put it back in the equation to get the y coordinate of the vertex.

anonymous · Answer

do I add that into the formula?

anonymous · Answer

How do I find -b/2a?

mertsj · Answer

-b/2a=-6/-2=3
The x coordinate of the vertex is 3.  Replace x with 3 and find y.

anonymous · Answer

y=15?
