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.

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 sent 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 each trip. This function consists of only the ordered pairs (52,3), (72,4), (86,5), and (105,6). What is the domain of this situation?

• {3, 4, 5, 6}

• {52, 72, 86, 105}

• 52 ≤ x ≤ 105

• 3 ≤ y ≤ 6

A Plane can carry a maximum cargo weight of 160,000 pounds. A company uses one of these planes to ship 2,000-pound containers. The total cargo weight is a function of the number of the containers in the plane. What is the greatest value in the domain for this situation?

• 8

• 8,000

• 160,000

• 80

For Sara’s birthday trip, she and her friends are renting a beach condo. The cost per person for the condo and gas can be found using the function c=56+9p. What is a reasonable range for this situation if there are at least 5 people but no more than 10 that can attend?

• {5, 6, 7, 8, 9, 10}

• {101, 110, 119, 128, 137, 146}

• 5 ≤ x ≤ 10

• 101 ≤ y ≤ 146
