Name the vertex and axis of symmetry for each quadratic function. Tell wherther the parabola opens up, down, left, or right.
\n" ); document.write( "x=2y^2+4y+5
\n" ); document.write( "--------------
\n" ); document.write( "Since the y^2 term is positive the parabola opens to the right.
\n" ); document.write( "-------------------
\n" ); document.write( "Complete the square:
\n" ); document.write( "2(y^2 + 2y + 1) = x - 5 + 2
\n" ); document.write( "2(y+1)^2 = x-3
\n" ); document.write( "Vertex: (3,-1)
\n" ); document.write( "Axis: y = -1
