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

*If the value repeats you only have to list it once*

• D: {1, -3, -4,}

  R: {0, 1, 2, -4}

• D:{0, 1, 2, -4}

  R:{1, -3, -4}

• D:{0, 1, 2, 3, 4}

  R:{1, -3, -4}

Solve:
2(2x + 3) = -6(x + 9)

• 1.2
• 6
• -6
• 7.5

(20ab) ÷ (a-b)² if a = 4 and b = -2

• 40/3

• 40

• -40/9

• -13

Which of the following is not a function?

• {(0,1), (1,2), (2,3), (3,4)}

• {(0,2), (1,3), (4,3), (1,2)}

• {(1,3), (4,2), (2,0), (3,4)}

• {(1,2), (2,2), (3,2), (4,2)}

-p − 4p > -10

• p > -2
• p > 2

• p < 2

Solve:
-8(x - 3) - 4x < 108

• x > -38
• x > -14
• x > -7
• x < -38

• n < 1
