Domain and Range from situations

Hector’s service club is raising money by wrapping presents in the mall. The function f(x) = 3x describes the amount of money, in dollars, the club will earn for wrapping x presents. They only have enough wrapping paper to wrap 1000 presents. What is an appropriate domain?

• 1000≤x≤0
• x≥1000
• 0≤x≤1000
• x≤3000
