have passed, x.
Type the correct answer in the box.

Answer 1

The function rule for the relationship between the amount of plant food remaining and the number of days that have passed can be represented as f(x) = a - kx, where a is the initial amount of plant food and k is the rate of consumption per day.

Step-by-step explanation:

The function rule for the relationship between the amount of plant food remaining, f(x), and the number of days that have passed, x, can be represented as:

f(x) = a - kx

Where:

• f(x) is the amount of plant food remaining
• x is the number of days that have passed
• a is the initial amount of plant food
• k is the rate at which the plant food is consumed per day
