Question

1. a function shows the number of tickets sold for a school play. a. {…, -2, -1, 0, 1, …} b. {0, 1, 2, 3, …} c. {0.1, 0.2, 0.3, …} d. {1, 2, 3, 4, …}

Explanation:

The number of tickets sold for a school play can be 0 (if no tickets are sold) or a positive integer (1, 2, 3, ...). Let's analyze each option:

• Option A: Includes negative integers, which don't make sense for the number of tickets (you can't sell a negative number of tickets).
• Option B: Includes 0 and positive integers, which is valid because you can sell 0 tickets (no sales) or more.
• Option C: Includes decimal numbers, but you can't sell a fraction of a ticket, so this is invalid.
• Option D: Starts at 1, but it's possible to sell 0 tickets, so this is too restrictive.

Answer:

B. {0, 1, 2, 3, ...}
