2. y=-x^2+6x-2 Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Identify the axis of symmetry, create a suitable table of values and sketch the graph...
1. y=x^2-5x+3
y = x^2-5x+(5/2)^2+3-(5/2)^2
y = (x-(5/2))^2 -(13/4)
y+(13/4) = (x-(5/2))^2
Vertex at (5/2,-13/4)
Axis of symmetry: x=5/2
----------------------
2. y=-x^2+6x-2
y+2-(3)^2 = -(x^2-6x+(3)^2)
y-7 = -(x-3)^2
Vertex: (3,7)
Axis of symmetry: x=3
