Question

{(ball, circle), (kite, diamond), (stop sign, octagon)}

Create an additional ordered pair that would make the relation no longer a function. In complete sentences, explain why the additional ordered pair affects the relation's ability to be a function.

Answer 1

a function maps one input (x) to one output (y)

Hence, an ordered pair that would make the relation "no longer a function",
would be a pair with one of the already seen x-values, but a different y-value.
