Which of the tables is NOT a function?

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**.
