Hi there,
\n" ); document.write( "f(x) = √x - 8; g(x) = x^2
\n" ); document.write( "(f o g) = (√(x^2) - 8
\n" ); document.write( "(f o g) = x - 8
\n" ); document.write( "(g o f) = (√x - 8)^2
\n" ); document.write( "(g o f) = (√x - 8)(√x - 8)
\n" ); document.write( "(g o f) = (x - 16√x + 64)
\n" ); document.write( "Hope this helps :-) \n" ); document.write( "

\n" );
