HELP THIS IS DUE TODAY Marinathe, Hezza, and Samuel had
been studying math all day. In the afternoon they took a break and went to the vending machine for a snack. After studying functions all afternoon, function vocabulary was on their minds. With money in hand, they stood in front of the machine. Samual said the machine was like a function machine with input and output. Marinathe said while there was input and output, she thought the machine was more like a relation machine instead of a function machine. Hezza said she thought it could be either, depending on how one thought about it.
