For the given functions f, g , and h , find f o g and state the exact domain of f o g o h .
\n" ); document.write( "f(x) = e^x
\n" ); document.write( "g(x) = logx
\n" ); document.write( "h(x) = x/x + 8
\n" ); document.write( "**
\n" ); document.write( "g o h=log[x/(x+8)]
\n" ); document.write( "f o g o h=e^log[x/(x+8)]
\n" ); document.write( "Domain of exponential functions=all real numbers
\n" ); document.write( "However,log[x/(x+8)]>0, or x>0
\n" ); document.write( "Denominator ≠ 0, so x ≠ -8 \r
\n" ); document.write( "\n" ); document.write( "Domain of f o g o h: (0,-8) U (-8,∞)
\n" ); document.write( "
\n" );
