If f(x) = 2x + 1 and g(x) = (x – 1)/2 , \n" ); document.write( "then f(g(x)) = f[(x-1)/2] = 2[(x-1)/2]+1 = (x-1)+1 = x \n" ); document.write( "================================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "=============== \n" ); document.write( " \n" ); document.write( " |
