Domain of Functions Practice

Is this table a function and how can you tell?

• Yes its a function because there are not variables for missing numbers

• No it's not a function because the y value 4 repeated

• No it isn't a function because the x value 2 is repeated

• No it's not a function because the x value 5 has 2 outputs.

The student council set its members on four field trips during the school year.  The number of buses needed to transport the members on each trip is a function of the number of members who went on the trip.  This function consists of only the ordered pairs (52, 3), (72, 4), (86, 5), and (105, 6).  What is the domain for this situation?

• {52, 105}
• {3, 4, 5, 6}
• {52, 72, 86, 105}
• {3, 4, 5, 52, 72, 86, 105}
