\n" ); document.write( "Hi
\n" ); document.write( "4y=2(x+1)^2-1
\n" ); document.write( " y = (1/2)(x+1)^2 - 1/4
\n" ); document.write( "the vertex form of a parabola, \"y=a%28x-h%29%5E2+%2Bk\" where(h,k) is the vertex
\n" ); document.write( " Pt(-1,-1/4) is the vertex
\n" ); document.write( "y-intercept, when x = 0
\n" ); document.write( "y = (1/2)*1 - 1/4
\n" ); document.write( "y = (1/2) Pt(0,1/4) the y intercept
\n" ); document.write( "x-intercept, when y = 0
\n" ); document.write( " 0 = (1/2)(x+1)^2 - 1/4
\n" ); document.write( " 1/4 = (1/2)(x+1)^2
\n" ); document.write( " 2/4 = x^2 + 2x + 1
\n" ); document.write( " 0 = x^2 + 2x + 1/2
\n" ); document.write( "\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
