Question

Initially, there were only 86 weeds in the garden. The weeds grew at a rate of 18% each week. The following function represents the weekly weed growth: f(x) = 86(1.18)x. Rewrite the function to show how quickly the weeds grow each day.

f(x) = 86(1.02)x; grows approximately at a rate of 0.2% daily
f(x) = 86(1.18)7x; grows approximately at a rate of 1.8% daily
f(x) = 86(1.02)7x; grows approximately at a rate of 2% daily
f(x) = 86(1.187)x; grows approximately at a rate of 0.18% daily
