Set 1: Exponential Functions

Choice A is correct. Choice A is the correct answer. Find the pattern and extend. 1. Growth Factor: $\frac{40}{10} = 4$ per day. 2. Formula: $A(d) = 10(4)^{d-1}$ where $d$ is the day. 3. Day 4: $A(4) = 10(4)^3 = 10(64) = 640$ acres. Strategic Tip: From day to day, multiply by the growth factor. Choice B is incorrect because this is day 3: $10(4)^2 = 160$. Choice C is incorrect because this doesn't match the pattern. Choice D is incorrect because this underestimates growth.
