\n" ); document.write( "\n" ); document.write( "You can try doing some of the work like this:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "roots: 3 and -1, so $\"%283%2B%28-1%29%29%2F2=1\"$ .
\n" ); document.write( "Axis of symmetry is x=1, and ...\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "... y-coordinate for vertex: $\"y=-%281-3%29%281%2B1%29=-%28-2%29%2A2=4\"$ .
\n" ); document.write( "Vertex is (1,4).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The parabola has vertex (1,4) and opens downward, and has x-intercepts -1, and 3.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "That is not all of the work for your question; but is most of it. \n" ); document.write( "
