Set 3: Exponential Functions

Choice A is correct. Choice A is the correct answer. Find the pattern and sum. 1. Pattern: $2, 8, 32, ...$ means multiply by 4 each hour: $A(h) = 2(4)^{h-1}$. 2. Calculate Each Hour: - Hour 1: 2 - Hour 2: 8 - Hour 3: 32 - Hour 4: 128 - Hour 5: 512 3. Total: $2+ 8 + 32 + 128 + 512 = 682$ acres. Strategic Tip: Sum a geometric series: $a(\frac{r^n - 1}{r - 1})$ or calculate each term. Choice B is incorrect because this is just hour 5, not the total. Choice C is incorrect because this is the sum of only hours 1-4. Choice D is incorrect because this would be hour 6.
