Question

If Included in the table, which ordered pair (-4,1) or (1,-4), would result in a relation that is no longer a function. Explain your answer.

Answer 1

(-4,1)

Explanation:

Ordered pair (-4,1) means that x = -4 and f(x) = 1

Ordered pair (1,-4) means that x = 1 and f(x) = -4

From the table, we can see that the function is already defined for x = -4, but it is not defined for x = 1. So, the point (1,-4) can be included into the function, but the point (-4,1) cannot.
