    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 ??

    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? :|

    -1/2 ?

    yes, domain = {-1/2} for sure.
