To change a question into passive voice, you typically reverse the order of the subject and the verb, and add a form of "be" before the main verb. For example, the active question "Did you finish your homework?" can become the passive "Was your homework finished by you?"
Has your homework been finished by you?
You can't: there is no passive form of this verb--just as there is no passive form of the verb "to go". Why? Because in order to have a passive voice, the verb in question must be transitive: i.e., take an object. You can't should a thing, or go a thing. But you can, for instance, stroke a thing. So you can say that the thing is/was stroked--passive.
