The following set represents a functional relationship between x and y:

Which of the following could be the missing ordered pair?

• (9, 14)

• (4, 2)

• (7,-6)

• (6, 7)

Which is true?

• It is a function because each input has exactly one output

• It is not a function because each output has more than one input

• It is not a function because it does not contain the origin

• It is not a function because the ratio between y and x is not constant

Select the following that represent a function:

• 
• 
• 
• 

• Function

• Not a function

• Function

• Not a function

• Function

• Not a function

• Function

• Not a function

Which is true?

• The mapping represents y as a function of x, because each y-value corresponds to exactly one x-value.

• The mapping does not represent y as a function of x, because two of the x-values correspond to the same y-value.

• The mapping represents y as a function of x, because each x-value corresponds to exactly one y-value.

• The mapping does not represent y as a function of x, because there are more x-values than different corresponding y-values.
