• f(x) = 20 + 1/3x
• f(x) = 20 - 1/3x
• f(x) = (x + 20) ÷ 3
• f(x) = (x - 20) ÷ 3

There were four school spirit assemblies last year. The number of teachers, y, needed to supervise each assembly is dependent upon the number of students attending, x. The solution set for the function describing the situation consists of the ordered pairs
(231, 9), (182, 7),(214, 8), and (252, 10). What is the domain of the situation?

• {7, 8, 9, 10}
• {182, 214, 231, 252}
• 7 ≤ y ≤ 10
• 182 ≤ x ≤ 252
