Domain and Range of Discrete Functions

Is the relation a function? Why?

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

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 only consists of 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}
