You can put this solution on YOUR website!
To find f(2), We have to set sqrt(x+1) = 2
\n" ); document.write( " $\"sqrt%28x%2B1%29=2\"$
\n" ); document.write( " $\"x%2B1+=4\"$
\n" ); document.write( " $\"x=3\"$
\n" ); document.write( "f(sqrt(x+1))=1/x
\n" ); document.write( "f(sqrt(3+1))= 1/3\r
\n" ); document.write( "\n" ); document.write( "Therefore f(2) = 1/3 \n" ); document.write( "

\n" );
