A shoe company used packing boxes to ship four orders to retail stores.  The number of packing boxes needed to transport the pairs of shoes is a function of the number of pairs ordered for each delivery.  This function consists of only the ordered pairs:
(44, 3),  (60,4),  (72, 5), and (88, 6)
What is the domain for this situation?

• {44, 60, 72, 88}
• {44, 88}
• {3, 4, 5, 6, 44, 60, 72, 88}
• {3, 4, 5, 6}

What is the range of the graph shown?

• {x ∣ -3 ≤ x < 5}
• {x ∣ -3 < x ≤ 5}
• {y ∣ -5 < y ≤ 3}
• {y ∣ -5 ≤ y < 3}
