In this activity, you will use multiple representations of relationships to identify key features and solve problems.

Ryan conducted a 6-day study observing the effects of an organic plant food on the growth of his sprouting bean plant. He tracked these two pieces of information:

the amount of plant food remaining in the container after each day’s feeding

the height of the plant over time

Part A

Ryan found that the amount of plant food remaining decreased an equal amount each day, and he used the entire 72 milliliters by the end of his study.

Part B

Ryan also found that he could model the height of his plant with the equation h = 0.5d + 4, where d is the number of days and h is the height in centimeters.


Part C (This is the question that I need help on....PLEASE?)

Explain the similarities and differences between the two relationships in this situation.
