let f(x) = ln(x), g(x) = √x + 1 and h(x) 1/x, be defined on their natural domains. Define the following functions and state the domain for each function, using set notation
\n" ); document.write( "(a)(f o g)(x) = f[g(x)] = f[sqrt(x)+1] = ln[sqrt(x)+1]
\n" ); document.write( "Domain: x >= 0
\n" ); document.write( "Range:: y >= 0
\n" ); document.write( "-------------------
\n" ); document.write( "(b)(g o f)(x) = g[f(x)] g[ln(x)] = sqrt[ln(x)+1]
\n" ); document.write( "Domain: x >= 0
\n" ); document.write( "Range: y >= 1
\n" ); document.write( "--------------------------
\n" ); document.write( "(c) g(x)h(x) = (sqrt(x)+1)(1/x) = [sqrt(x)+1]/x
\n" ); document.write( "Domain: x > 0
\n" ); document.write( "Range: ?
\n" ); document.write( "=================
