Hi
\n" ); document.write( "y=x^2+2x+1
\n" ); document.write( "this is in a general form of an equation for a parabola: y = ax^2 + bx + c
\n" ); document.write( "and the axis of symmetry is x = -b/(2a)
\n" ); document.write( "x = -1 is the axis of symmerty.
\n" ); document.write( ".
\n" ); document.write( "*Note: Vertex form of the equations would be:
\n" ); document.write( "y = (x + 1)(x + 1) = (x+1)^2
\n" ); document.write( ".
\n" ); document.write( "general vertex form of an equation for a parbaola is y = a(x - h)^2 +k
\n" ); document.write( "where (x.k) is the vertex
\n" ); document.write( ".
\n" ); document.write( "this parabola opens upward with a min value of 0, it's vertex is (-1, 0)
\n" ); document.write( "and range is [0, infinity)\r
