The vertex form of a parabola's equation is generally expressed as :
\n" ); document.write( " $\"+y=+a%28x-h%29%5E2%2Bk+\"$
\n" ); document.write( "where (h,k) is the vertex
\n" ); document.write( ".
\n" ); document.write( "You were given:
\n" ); document.write( " $\"y=-%28x-6%29%5E2-1\"$
\n" ); document.write( "which if we could rewrite as:
\n" ); document.write( " $\"y=-%28x-6%29%5E2%2B%28-1%29\"$
\n" ); document.write( "From inspection, because it is in \"vertex form\" we see that the vertex is at
\n" ); document.write( "(6,-1)\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
