find the domain of the composite function f of g. f(x)=x^2+9;g(x)=sqrtx-7
\n" ); document.write( "----
\n" ); document.write( "f[g(x)]
\n" ); document.write( "= f[sqrt(x)-7]
\n" ); document.write( "=(sqrt(x)-7)^2+9
\n" ); document.write( "= x-14sqrt(x)+49 + 9
\n" ); document.write( "= x -sqrt(x)+58\r
\n" ); document.write( "\n" ); document.write( "------
\n" ); document.write( "Domain: x >= 0
\n" ); document.write( "====================
