using the vertex form ___ y = a(x - 9)^2 - 8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting ___ 2 = a(0 - 9)^2 - 8 ___ 10 = 81a ___ 10/81 = a\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "expanding ___ y = (10/81)x^2 - (20/9)x + 2 \n" ); document.write( "

\n" );
