Question

31. The table shows a relation that is a function, where x
is the input and y is the output.

Answer 1

Answer: 4, 5, 6, and 7

Explanation:

In mathematics, a function is a relationship between inputs where each input is related to exactly one output.

So for the answer choices to work, they cannot have any of the x values that are already included in the table.

That eliminates 1, 2, and 3 as their x values are already in the table.

So the answer is 4, 5, 6, and 7
