Salary expectations: how do you answer? (Fresno)

I do not know whether to give a range or ask for theirs. I do not usually post, so bear with me. I also do not want to sell myself short. How do you research fairly?

Benefits matter too. A slightly lower rate with better coverage was better for me.

I gave a range based on local postings and said I was flexible depending on the whole package. They did not push back.
