Which set of values is a function?

• (9,5) (10,5) (9,-5) (10,-5)
• (3,4) (4,-3) (7,4) (3, 8)
• (6,-5) (7, -3) (8, -1) (9, 1)
• (2, -2) (5, 9) (5, -7) (1, 4)

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

• D: {-4, -3, 1}

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

• D:{-4, 0, 1, 2,}

  R:{-4, -3, 1}

• D:{0, 1, 2, 3, 4}

  R:{1, 3, 4}

What set of numbers represents the RANGE in the graph?

• {-3, 0, 2, 3, 4}

• {-3, -1, 1, 2, 3, 4}

• {-3, -2, -1, 0, 1, 2, 3, 4}

• {0, 1, 2, 3, 4}

What set of numbers represents the DOMAIN of the graph?

• {-3, -1, 1, 2, 3. 4}

• {-3, -2, -1, 0, 1, 2, 3, 4}

• {-3, 0, 2, 3, 4}

• {0, 1, 2, 3, 4}

Given

f(x)= 2x² + 5x - 17, find f(-2).

• f(-2) = -11

• f(-2) = -19

• f(-2) = -35

• f(-2) = -43

Evaluate f(x) = 5x + 9 when x = -11

• f(-11) = 64

• f(-11) = -46

• f(-11) = -4

• f(-11) = -55

Solve for a:

-3a + 8 = 14

• a = -2

• a = -7.5

• a = 2

• a = 6

Solve for x:

2x - 3 + 4x = 27

• x = 12

• x = 4

• x = 5

• x = 15

Solve for x:

7(2x - 4) = 42

• x = 5

• x = 8

• x = 2

• x = 9

Which Statement best describes the solution to the equation.

3(x - 8) = 3x - 24

• No Solutions

• One Solution, x = 3

• Infinitely Many Solutions

• One Solution, x = 0
