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: $45\le y\le65$

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

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

• D: {-4, 0, 1, 2}
  R:{-4, -3, 1}
• D: {0, 1, 2, 3, 4}
  R:{1, -3, -4}
• D: {0, 1, 2, -4}
  R: {1, -3, -4, 1}
