Quiz Lessons 1.1-1.3 (Pd 6)

Identify the range of the following function when given the domain { 2, 3, 10}:
y = 4x - 12

• 4, 12, 20

• -20, 0, 28

• -4, 0, 28

• 8, 12, 40

What is the RANGE?

• {-3, 3]

• all real numbers

• [-4, 5]

• [-4, ∞)

What is the DOMAIN?

• [0, ∞)

• (-∞, 0)

• All real numbers

• {0, 1, 2, 3, 4,...}

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

• D: {1, -3, -4,}
  R: {0, 1, 2, -4}

• 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}

Does the graph represent a function?

• Yes, because the vertical line test shows there are no repeating input values

• No, because the vertical line test shows there are repeating input values

All of the y values or outputs are called what?

• Domain

• Range

All of the x values or inputs are called what?

• Domain

• Range

Is the relation a function? Why?

• Yes, because the x-value 11 has two y-values pair with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the x-value 11 has two y-values pair with it.

• No, because each x-value has only one y-value paired with it.

What is the value of f(-5)?

• -2

• 2

• 4

• 0

For what value of x does f(x) = -2?

• 0

• -5

• 3

• -3
