Question 93185: I need help to solve these problem I am having problems figuring it out.
Identify the axis summetry, greate a suitable table of value, then sketck the graph(include the axis of summetry).
The first one is y=x^2-4x
and the other one is y= -x^2+3x-3
thanks a million

I need help to solve these problem I am having problems figuring it out.
Identify the axis summetry, greate a suitable table of value, then sketck the graph(include the axis of summetry).
The first one is y=x^2-4x
Y=(X-2)^2-4
HENCE X=2 IS THE LINE OF SYMMETRY
X...........-2......0...........2.........4.........6....ETC
Y=X^2-4X....12......0..........-4.........0.........12...ETC

and the other one is y= -x^2+3x-3 = 1.5^2-3-[X^2-2*X*1.5+1.5^2]
Y=-0.75-(X-1.5)^2
X=1.5 IS LINE OF SYMMETRY
X...............-3.........-1.........0.........1.........3...ETC.
Y=-X^2+3X-3.....-21........-7........-3........-1........-3...ETC
