1. Let's analyze the relationship between the variables:

The amount of fertilizer used (f) is something that a gardener or a person taking care of the plants can choose to apply. They can decide to use more or less fertilizer depending on various factors like the type of plants, soil conditions, etc.

The growth rate of plants in centimeters per week (r) is expected to be affected by the amount of fertilizer used. Different amounts of fertilizer (f) can lead to different growth rates (r). For example, if more fertilizer is used (increase in f), it might result in a higher growth rate (increase in r), although there are limits and other factors at play too.
