\n" ); document.write( "\n" ); document.write( " $\"f%28x%29+=+-7%28x+-+8%29%5E2+%2B+10\"$ \r
\n" ); document.write( "\n" ); document.write( "it's already written in vertex form $\"f%28x%29+=+a%28x+-+h%29%5E2+%2B+k\"$ where $\"h\"$ and $\"k\"$ are coordinates of vertex\r
\n" ); document.write( "\n" ); document.write( "as you can see $\"h=8\"$ and $\"k=10\"$ , so vertex is at ( $\"8\"$ , $\"10\"$ ) \n" ); document.write( "
