Use the vertex form,
\n" ); document.write( " $\"y=a%28x-h%29%5E2%2Bk\"$
\n" ); document.write( " $\"y=a%28x-5%29%5E2%2B4\"$
\n" ); document.write( "Use the point to find $\"a\"$ ,
\n" ); document.write( " $\"2=a%284-5%29%5E2%2B4\"$
\n" ); document.write( " $\"2=a%2B4\"$
\n" ); document.write( " $\"a=-2\"$
\n" ); document.write( ".
