The total cost in dollars, c, to purchase video games online can be found using the function c = 16.95x + 4.75, where x is the number of video games purchased.  If at least 4 games but no more than 7 games are purchased online, what is the range of the function for this situation?

• {4, 5, 6, 7}
• 4 ≤ x ≤ 7
• 72.55 ≤ c ≤ 123.50
• {72.55, 89.50, 106.45, 123.40}

What is the Range of the situation?

• All real numbers greater than or equal to 0 and less than or equal to 28
• All real numbers greater than or equal to 0 and less than or equal to 9
• All real numbers less than or equal to 28
• All real numbers less than or equal to 9

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}

What is the Range?

• -3 ≤ y < 2
• -3 < y ≤ 2
• -7 ≤ y ≤ 2
• -7 ≤ y < 2

The amount of money that Li spends on video games depends on how many games he purchases.  If Li has at most $90 to spend on games for his Xbox 360 and the games cost $22.50 each, what is the domain of this function?

• {0 ≤ x ≤ 90}
• {0 ≤ x ≤ 4}
• {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
• {0, 1, 2, 3, 4}
