Answer 1

Answer:

The table that represents a function is;

$\text{Table C}$

Explanation:

Given the table A,B,C and D.

We want to select the table that represents a function.

For a table to represent a function each input must not have more than one possible value of output.

For table A, the input 8 has two different outputs (-8 and -9). Therefore, it is not a function.

For table B, the input 7 has two different outputs (12 and 13). Therefore, it is not a function.

For table D, the input 10 has two different outputs (0 and 10). Therefore, it is not a function.

For table C, No input has more than one output. Therefore, it is a function.

The table that represents a function is;

$\text{Table C}$
