Answer 1

To determine which of the tables is NOT a function, we need to check for each table whether any input (x value) corresponds to more than one output (y value).

Let's analyze each table:

Table A:

• (0, 5)
• (3, 5)
• (9, 7)
• (5, 0)

Each x value is unique, so Table A is a function.

Table B:

• (3, 5)
• (0, 7)
• (1, 9)
• (3, 0)

In this table, the x value "3" corresponds to two different y values (5 and 0). Therefore, Table B is not a function.

Table C:

• (1, 5)
• (8, 1)
• (7, 6)
• (3, 3)

Each x value is unique, so Table C is a function.

Based on this analysis, the table that is NOT a function is Table B.
