Answer:
B: This relationship is not a function because more than one amount of plant food remains each day
Step-by-step explanation:
It is given that Ryan did an experiment by observing the effects of plant food and the growth of the sprouting bean plant. He made a note of the height of the bean plant and the amount of food remaining in the container for the plant after feeding each day.
Thus he observed that the plant food in the container decreases by an equal amount everyday as the bean plant grew. Thus this states that it is not a function between the two as there are more than one plant food remaining each day for the plant.
A relationship is a function when one element belongs to one thing.
