What is the domain of the function? (using interval notation)

• all real numbers

• (-2, 4)

• [-2,4]

• [-6,3]

What is the range of this function? (using interval notation)

• [-6,3]

• (-6,3)

• all real numbers

• [-2,4]

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.

• 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
