You can put this solution on YOUR website! Identify the axis of symmetry, create a suitable table of values, then sketch the graph (including the axis of symmetry).
y=-x^2+3x-3
------------------
Complete the square on the x-terms and keep the equation balanced:
-x^2+3x = y+3
-(x^2-3x+(3/2)^2) = y+3-(3/2)^2
-(x-(3/2))^2 = y+(3/4)
---------
Axis of Symmetry: x=(3/2)
----------
Table:
x=0, then y = -3
x=1, then y = -1
x=2, then y = -1
x=3, then y = -3
------------------
Graph:
