• {x| -2 < x < 4}
• {x| -2 ≤ x ≤ 4}
• {x| -6 ≤ x ≤ 3}

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.

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.

Which of the following best describes a function?

• A special relationship where each x and y are individually paired
• A special relationship where each x value has only one y value 
• A special relationship where each y value has only one x value 
• A special relationship where each the x and y value and always equal 

What is the Domain?

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

What is the domain?

• {-4, -1, 0, 2, 7}
• {-5, -4, -1, 0, 1, 2, 4, 7}
