Let's analyze the question.

A table represents a function if every x-value corresponds to exactly one y-value (no x-value is repeated with a different y-value).

Given Table:

From the table:

• The x-value 8 is repeated, but it corresponds to two different y-values: 5 and 8.

This violates the rule for functions that says each x-value must pair with only one y-value. Hence, this table does not represent a function.

Correct Answer:

D. No, because one x-value corresponds to two different y-values.

Would you like me to explain this in more detail or clarify further?

Here are 5 related questions for deeper understanding:

1. What is the definition of a function in terms of x- and y-values?
2. How can you quickly identify whether a table represents a function?
3. What is the difference between a function and a relation?
4. Can two different x-values correspond to the same y-value in a function? Why?
5. How would this concept apply to a graph representation?

Tip: A quick way to check for functions is the vertical line test for graphs or ensuring no x-values repeat with different y-values in tables.
