Initially, there were only 3 weeds at a park. The weeds grew at a rate of 5% each week. The following function represents the weekly weed growth: f(x) = 3(1.05).
To rewrite the function to show how quickly the weeds grow each day, we need to convert the weekly growth rate to a daily growth rate. Since there are 7 days in a week, we divide the weekly growth rate by 7 to get the daily growth rate.
The daily growth rate can be calculated as follows:
f(x) = 3(1.05) / 7
To calculate this rate as a percentage, we multiply the result by 100.
Therefore, the function representing the daily weed growth is f(x) = 3(1.05) / 7, and the rate of growth is (3(1.05) / 7) * 100%.
