\n" ); document.write( "g(x) = 2x - 1
\n" ); document.write( "g(x) = 2( x ) - 1
\n" ); document.write( "g(f(x)) = 2( f(x) ) - 1
\n" ); document.write( "g(f(x)) = 2( 3x+1 ) - 1
\n" ); document.write( "g(f(x)) = 2(3x)+2(1) - 1
\n" ); document.write( "g(f(x)) = 6x+2 - 1
\n" ); document.write( "g(f(x)) = 6x+1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Explanation:
\n" ); document.write( "We start with the outer function g(x). Replace each copy of x with f(x).
\n" ); document.write( "Then plug in f(x) = 3x+1 and simplify.
\n" ); document.write( " \n" ); document.write( "
