I have a question about the limit problem. I need find limit if it exists.(adsbygoogle = window.adsbygoogle || []).push({});

lim x (approach to 4) (3x+square root x-4).

If I plug number for x=4, I get 12. But I am concern about square root. Do I need find one-sided limit from x approach to 4+ and x approach to 4-. Or 12 will be the correct answer?

Thanks, everyone
