Write the quadratic function in vertex form then graph the function. y=2x^2-2x+1
\n" ); document.write( "this is what i have so far y=-2(x-2)+1
\n" ); document.write( "I don't really know how to tell what is h and what is k.\r
\n" ); document.write( "\n" ); document.write( "..
\n" ); document.write( "y=2x^2-2x+1
\n" ); document.write( "Standard form for a second degree equation which is a parabola:
\n" ); document.write( "y=(x-h)^2+k, with (h,k) being the (x,y) coordinates of the vertex.
\n" ); document.write( "completing the square,
\n" ); document.write( "y=2(x^2-x+1/4)+1-1/2
\n" ); document.write( "y=2(x-1/2)^2+1/2
\n" ); document.write( "This is a parabola that opens upwards with the vertex at (h,k)=(1/2,1/2)
\n" ); document.write( "see the graph of this parabola below:
\n" ); document.write( "..\r
