You can put this solution on YOUR website!

  \r\n" );
document.write( "\r\n" );
document.write( "so f+g(x)=(3x)/(x+2)+2/(x+2)=(3x+2)/(x+2)\r\n" );
document.write( ":\r\n" );
document.write( "(f+g)(2)=(3(2)+2)/(2+2)=8/4=2\r\n" );
document.write( ":\r\n" );
document.write( "the domain is all real numbers except -2 because -2+2 in the denominator is not allowed. you would be dividing by zero which is undefined\r\n" );
document.write( "
