CHS9 Unit 2 Review

Gracie's service club is raising money by wrapping presents in the mall. The club earns 3 dollars per wrapped present. They only have enough wrapping paper to wrap 1000 presents. What is the reasonable domain?

• {0, 1, 2, 3, ... , 1000}

• {0, 3, 6, 9, ..., 3000}

• 0 ≤ x ≤ 1000

• 0 ≤ x ≤ 3000

Before a bowler rolls her first ball, 10 pins are standing. The number of pins that will be left standing, y, is a function of the number of pins she knocks down. What is the reasonable range of the function?

• { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }

• { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }

• y ≤ 10

• 0 ≤ y ≤ 10

A student lives 3 miles from the library. He is riding his bike to the library. The distance he has remaining, y, is a function of how long he has been riding his bike. What is the reasonable range of the function?

• {0, 1, 2, 3}

• 0 ≤ y ≤ 3
