Aiden says that both tables represent functions.
Beau says table B does not represent a function since each x-value has the same y-value.
Cecilia says table B represents a function since each input has one output.
Darrell says table A represents a function since each output has one input.
Emma says table A would represent a function if the point (10,−4) was removed.
Faith says if the point (−5,10) was added to table B, it would no longer represent a function.

CLUE #1
Lydia's representation is not a function because the input of 0 has more than one output.
CLUE #2
Hayden's representation is not a function because the input of 3 has more than one output.
CLUE #3
If the point (0,4) was added to Travis's representation, it would no longer represent a function.
CLUE #4
If (2,0) was added to Zoe's representation, it would remain a function.
