y = 2x^2 - 4x. for each function give the equation of the axis of symmetry, the coordinates of the vertex and the x- and y- intercepts of its graph
\n" ); document.write( "---------------
\n" ); document.write( "y=2(x^2-2x)
\n" ); document.write( "Complete the square as follows:
\n" ); document.write( "2(x^2-2x+1)=y+2
\n" ); document.write( "2(x-1)^2 = y+2\r
\n" ); document.write( "\n" ); document.write( "-------------
\n" ); document.write( "Vertex: (1,-2)
\n" ); document.write( "Axis of symmetry: x=1
\n" ); document.write( "y-intercept: (0,0) Get this from the original equation; let x=0, then y=0.
\n" ); document.write( "x-intercept: From original; let y=0, then 2x(x-2)=0;(0,0),(2,0) x-intercepts.
\n" ); document.write( "------------
