Which of the tables represents a function? table a input output 3 1 3 4 2 3 table b input output 2 7 5 6 2 9 table c input output 1 5 7 2 7 3 table d input output 3 4 1 5 8 5 table a table b table c table d

Table D.

Step-by-step explanation:

According to the laws of a function, one input can not have multiple outputs.

3 - 1

3 - 4

2 - 3

Three has more than one output; 1 and 4.

2 - 7

5 - 6

2 - 9

Two has more than one output; 7 and 9.

1 - 5

7 - 2

7 - 3

Seven has more than one output; 2 and 3.

3 - 4

1 - 5

8 - 5

While i'm not sure what the function is, it has no repeating input-outputs (only outputs). I may not be 100% correct, as i'm taking the test right now in fact, but I certainly hope this is the right answer (for the both of us!) I'll edit my answer if it's indeed incorrect.
