Algebra.Com's Answer #48777 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! 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( "------------ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
