For the function (0,1), (1,-3), (2,-4), & (-4,1), which choice gives the correct domain & range?

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

Is this table a function and how can you tell?

• Yes its a function because there are not variables for missing numbers

• No it's not a function because the y value 4 repeated

• No it isn't a function because the x value 2 is repeated

• No it's not a function because the x value 5 has 2 outputs.

Is this mapping a function and how can you tell?

• Yes its a function cause all the numbers have lines

• No it's not a function because there a 5 in both ovals

• No it's not a function because the x value 5 has 2 outputs.

• No it's not a function because the y value 5 has 2 inputs.

What is the Domain?

• {-3, -1, 1, 3, 5, 7, 9}
• {-3, -2, -1, 0, 1, 2, 3}
• -3 ≤ x ≤ 3
• -3 ≤ x ≤ 9

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.
