Domain and Range of a Function

Sprinkles the pony is selling t-shirts for a fundraiser. He spent $500 on 200 t-shirts and is selling each shirt for $12. His profit is a function of the number of t-shirts he sells. Which set of values represent the domain?

• {all real numbers}

• {0 ≤ x ≤ 12}

• {0 ≤ x ≤ 200}

• {0, 1, 2, 3, ...200}
