Which of the tables represents a function?

Question

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

Answer 1

You cannot have the same input mapping to multiple outputs, as in Table C and A. You can have different inputs mapping to the same output as in Table D. And of course, you can have unique input-output mapping as in Table B

Answer 2

So, what's the answer? @bobpursley

Answer 3

I belive the answer is D as a kid on brainly gave a good explanation

Answer 4

here is the link: h t t p s : / / b r a i n l y . c o m / q u e s t i o n / 3 4 0 9 7 7 9 (take away spaces)

Here is the explanation:

Answer:

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.
