Question

Is the relation below a function? Explain.



{ (-2, 4) , (-1, 3) , (0, 2) , (-2 , 0) , (1, 1) }

Answer 1

To determine if the relation is a function, we must check if each x-value has a unique y-value.

In this relation, each x-value has a unique y-value. For example, for x = -2, y = 4.

Therefore, the relation is a function.
