Boolean function of Degree n

:(

Good Afternoon, I need some help, I am trying to find out how to go about putting together a table when I am asked how many boolean functions are there for a specific degree such as 5 or 8 etc. In the text it gives a table with boolean functions of degree two. Do I use this table or create a new one? Truth Table?

Sorry if this is a novice question, but I am taking this course in discrete math online and it is hard to explain much less to get through. Any and all help would be a great help, the professor who is leading the course. Does not provide much help.

Thanks, Mary Covington Elkmont, AL:confused:
