Question

If F = {(2, 5), (3, 4), (4, 6), (2, 1), (7, 2)}, then F is a function.

true or false

Answer 1

HELLO, THERE!

The answer is False! :)

Answer 2

Hello!

In a function, each input must have ONE and ONLY one output. As you can see, 2 has two outputs, 5 and 1.

Therefore, it is not a function. It is false.

I hope this helps!
