Domain help

Usually domain names are pretty cheap, however, you also have to pay for the server space, this usually ends up costing about $60-$80 per year depending on the server and how much space. Another option is to use google's blogger service - create a blogspot blog and then use Google Domains (or google sites, I can't remember the name of it) to create your domain name - it costs $10 - and then you have it directed to your blog, which is actually easier to maintain than a regular html website and you can still do some pretty sweet stuff if you practice and play around with it.

Domain is the set of all possible input values for which a function is defined. wat

Thanks man, I'll do this, sounds like less of a hassle haha

For the equation y=1337x, the domain is all reals. 

I'd recommend just using blogger for a little while before paying for the domain just to be sure you like it and can do what you want with it - although you do still own the domain for a year, it's a lot easier to just not buy it yet then to move it around after buying it.
