You can put this solution on YOUR website!
r o q merely means r(q(x)) and so you are looking to evaluate r(q(1)).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "q(1) is the input into r(x).
\n" ); document.write( " $\"r%28x%29=+sqrt+%28x%2B5%29\"$ , _____you did not show exactly what you meant,
\n" ); document.write( " $\"r%28q%28x%29%29=sqrt%28%28x%5E2%2B3%29%2B5%29\"$
\n" ); document.write( "Setting x=1, $\"r%28q%281%29%29=sqrt%281%5E2%2B3%2B5%29=sqrt%289%29=%2B-+3\"$ \n" ); document.write( "

\n" );
