Which of the following scenarios does not represent a function?

Question

A. Kirin saves $5 from her allowance every week.

B. Brent weighs himself each week. One week, he weighs himself twice.

C. Amanda runs two circuits around the park in 45 minutes.

D. DeSean belongs to a DVD club where he receives 2 DVDs every month.

I know the answer is either B or C. However, I'm leaning more towards B... Is this correct?

Answer 1

Has anyone seen this? :(

Answer 2

It would be B as Brent weighs himself twice on one week ONLY thus ruining the pattern of the function. Hope this helps!

Answer 3

I actually already turned it in, but I figured I would let you know you were correct! :)

Answer 4

Thanks for letting me know!
