domain x direction
range y direction
i doubt there would be a domain
range is quite easy to determine

Yeah, I know what the domain and range are, but I'm not sure what to write.

range can be written like this
\[(\infty,\infty)\]

you find domain and range of a 'function'
x=1/2 is an equation, not a function.
is your function : f(x) =x+1/2 ??

or f(x) =1/2 ??

No. Here is the exact problem.

x=1/2 is not a function because you have 2 or more values of 'y', you have same value of 'x'

And @completeidiot, is there another way to write that? I don't remember that. All real numbers? And should I just put "n/a" for the domain?

all real numbers is a valid answer

Then what about the domain? :
