A function is defined using the set of ordered pairs: {(2, 4), (7, -3), (0, 5), (9, 2)}. If the point (7, 6) was added to the given set, would it still be a function?

• Yes, because each x-value is unique.

• No, because the x-value 7 would have two different y-values.

• Yes, because the y-values do not affect the function.

• No, because adding any point changes the function.
