Question 104023: Tutor,
I have one last problem and I am having difficulty getting the answer. I think I am wrong on the negatives and possitives. My graph does not look right.
Indetify the axis of symmetry and create a table of values and graph.
y= -x^2 + 6x - 2
My answer does not look right to me could you please help me with this? Thank you in advance.

Indentify the axis of symmetry and create a table of values and graph.
y= -x^2 + 6x - 2
---------

-----------------
Table:
If x=0, y=-2
If x=1, y=3
If x=2, y=6
If x=3, y=7
If x=4, y=6
If x=5, y=3
etc.
---------------
Axis of symmetry:
-x^2+6x = y+2
-(x^2-6x+?) = y+2+?
Complete the square on the x-terms:
-(x^2-6x+9) = y+2-9
Factor:
-(x-3)^2 = y-7
--------------------
Vertex: (3,7)
Axis: x = 3
----------------
Cheers,
Stan H.
