Question 80817
i need to identify the axis of symmetry and create a sutible table of values then graph the equation i can graph the equation i need help doing it. 
y=x^2-4x
i need to identify the axis of symmetry and create a sutible table of values then graph the equation i can graph the equation i need help doing it. 
y=x^2-4x
-------------
Axis of symmetry is x=-b/2a = -(-4)/2= 2
It is the line x=-2
----------------------
If x=2, y=-4
If x=1 or 3, y=-3
If x=0 or 4, y=0
If x=-1 or 5, y=5
etc.

{{{graph(400,300,-10,10,-10,10,x^2-4x)}}}
