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}

Is this mapping a function and how can you tell?

• Yes its a function cause all the numbers have lines

• No it's not a function because there a 5 in both ovals

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

• No it's not a function because the y value 5 has 2 inputs.
