I mean that 0.5 could be y

So what really is meant by the domain? Is it asking for all possible values of y?

[b]1. what is the domain of the function k(y)=1/(2y+1)? Express your answer in interval notation [b]2. [b]3. I find that 0.5 is a possibility in this function, but since i have not done functions at school, i do not really know much more of this question.
