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 for this situation?

• {52, 105}

• {3, 4, 5, 6}

• {52, 72, 86, 105}

• {3, 4, 5, 6, 52, 72, 86, 105}

• All real numbers

• All real numbers greater than or equal to -8

• All real numbers greater than or equal to -7

• All real numbers greater than or equal to 0

Which statement is true?

• The range is the set of all real numbers less than 0.

• The domain is the set of all real numbers greater than -4.

• The domain is the set of all real numbers less than -4.

• The range is the set of all real numbers greater than 0.

The total cost in dollars to buy uniforms for the players on a volleyball team can be found using the function c = 34.95u + 6.25, where u is the number of uniforms bought. If there are at least 8 players but not more than 12 players on the volleyball team, what is the domain of the function for this situation?

• 0 < u ≤ 12

• 0 < c ≤ 425.65

• {8, 9, 10, 11, 12}

• {285.85, 320.80, 355.75, 390.70, 425.65}

What is the range of this situation?

• All real numbers greater than or equal to 0 and less than or equal to 9

• All real numbers greater than or equal to 0 and less than or equal to 28

• All real numbers less than or equal to 28

• All real numbers less than or equal to 9
