Its easy, you can check by writing robots.txt after your domain name. For Example- http://www.domainname.com/robots.txt Also, you can check on google webmaster tool > select your website > Crawl > robots.txt Tester. Hope this will help you.

you can simple type "example.com/robots.txt" if it's added it will appear or it will redirect homepage if server didn't found it's very easy to add there but it's a important file you can give the instruction to google that which pages or modules you don't want crawl on search engine.
just type the domain name yourdomain.com/robots.txt you will see if file is added if not you can add in root directory of your domain
