  Range: 21 < y< 27

• Domain: 3 < x < 6

  Range: 21 < y < 27

• Domain: {3, 4, 5, 6}

  Range: { 21, 23, 25 , 27}

• Domain: { 21, 23, 25 , 27}

  Range: {3, 4, 5, 6}

A student is taking a test that has 20 questions on it. The student's score is a function of how many questions he misses: f(x)=100-5x, where x is the number of questions incorrect. If the student misses between 7 to 11 questions, What is the domain and range?

• Domain: {7, 8, 9, 10 ,11}

  Range: {65, 60 55, 50, 45}

• Domain: {7, 8, 9, 10 ,11}

  Range: {45, 50, 55, 60, 65}

• Domain: 7< x<11
  Range: 45<y< 65

• Domain: $7\le x\le11$
  Range: $45\le y\le65$

What is the domain of the graph shown?

• {-2, -1, 0, 1, 2, 3, 4}

• {2, 3, 4}

• 2 ≤ y ≤ 4

• -2 ≤ x ≤ 4

Give the range of the set of ordered pairs: (2, 11), (9, -3), (7, 21), (-8, 6)

• {2, 9, 7, -8}

• {-3, 6, 11, 21}

• -8 < x < 9

• -3 < y < 21

What is the Domain of the situation?

•  $0\le x\ \le9$  

•  $0<x<9$  

•  $0<x<28$  
  

•  $0\le y\le28$ 

A pizza shop sells pizza for $7.50 each plus $1.25 per topping. The total price of the pizzas can be determined by the function P(t) = 7.5 + 1.25t, where te is the number of toppings orders and P(t) is the total price of the pizza. If the shop has a delivery policy that all orders must have a minimum of 2 toppings and maximum of 8 toppings for a delivery, what is the range

• {10, 11.25, 12.50, 13.75, 15, 16.25, 17.50}

• {2, 3, 4, 5, 6, 7, 8}

• 10 ≤ P(t) ≤ 17.50

• 0 ≤ P(t) ≤ 17.50

The total cost in dollars to buy uniforms for the players on the volleyball team can be found using the function c = 34.95u + 6.25, where u is the number of uniforms bought.  If there are at least 8 players but not more than 12 players on team, what is the domain of the situation?

• 0 < u ≤ 12
• 0 < c ≤ 425.65
• {8, 9, 10, 11, 12}
• {295.85, 320.80, 355.75, 390.70, 425.65}
