Im having a little trouble understanding what the difference between a range and codomain is. For example, for the function [tex]f(x) = \frac{3}{{2x - 2}}[/tex], i understand that the domain is [tex]\{ x \in R:x \ne 1\}[/tex]. Now, i also believe that the possible values that can be outputted by the function is given by

[tex]

\{ f(x) \in R:f(x) \ne 0\}

[/tex]. Is this the codomain or range?

Thanks in advance,

Dan.
