A1 - Domain and Range

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

• D: {x: 1, -3, -4,}

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

• D: {x: 0, 1, 2, -4}

  R: {y: 1, -3, -4}

• D: {x: 0, 1, 2, 3, 4}

  R: {y: 1, -3, -4}

Identify the domain of the following relation:

• D: {x: -6, 14, 2, 28}

• (-6,14), (0,32), (2,38), (4,44)

• D: {x: -6, 0, 2, 4}

• D: {x: 14, 32, 38, 44}

What is the range of the mapping?

• R: {y: 1, 2, 4}

• R: {y: 0, 1, 2, 3}

• R: {y: 0, 3}

• R: {y: 1, 4}

What is the range of the following graph?

• R: {y: -5, -1, 0 , 1, 5}

• R: {y: -4, -2, 0, 3, 6}

• (-4, 1) ( 6, 0)

• (6, 0)

What is the domain of the graph?

• D: {x: 1 ≤ x ≤ 4}

• D: {x: 1 < x < 5}

• D: {y: 1 ≤ y ≤ 4}

• D: {y: 1 < y < 5}

What is the Domain?

• $-3<x\le\infty$

• $-3\le x\le3$

• $-4\le y\le5$

• $-3<y\le3$
  

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.

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

What is the range?

• {3, 4}

• {1, 2, 3}

• {1, 2, 3, 4}

• {1, 3}

Is this graph a function or not a function? 

• Function
• Not a Function
