Jennifer and Shelly were discussing functions and trying to identify weather or not this data set was a function.
Shelly argued that this was a function because each arrow went to a number in the y column, therefore each input had an output.
Jennifer disagreed. She believes that this data does not display a function because each input does not have only one output.
Determine who is correct. Choose the answer that BEST describes the reasoning (remember there could be more than one correct answer, but choose the BEST answer)
A) Shelly is correct because this represents a function where each input has exactly one output.
B) Jennifer is correct because it is not a function.
C) Jennifer is correct because a function assigns one input to exactly one output and 3 has more than 1 output.
D) Shelly is correct, this is a function.
A) (-1,-7)
B) (7,-1)
C) (0,0)
D) (-1,7)
