Answer:

B

Explanation:

You want to identify the table that represents a function.

Function

A function maps any x-value to a single y-value. If a table has any repeated x-value, it does not represent a function.

Tables

  1. x-values 6 and 7 are repeated
  2. no repeated x-value. This table is a function.
  3. x-values 3 and -3 are repeated
  4. x-values 4 and 5 are repeated

__

Additional comment

It can be easier to see if x-values are repeated if they are written in increasing order.

  • 6, 6, 7, 7
  • -3, -2, 2, 3 . . . . no repeats
  • -3, -3, 3, 3
  • 4, 4, 5, 5
