Set 11: Exponential Functions

Choice B is correct. Choice B is the correct answer. Match parameters to $y=ab^x$. 1. Initial Value: $a = 4$. 2. Growth Factor: $b = 1.5$. 3. Combine: $y = 4(1.5)^x$. Strategic Tip: $a$ is outside, $b$ is inside the parenthesis. Choice A is incorrect because it swaps $a$ and $b$. Choice C is incorrect because the factor is 0.5. Choice D is incorrect because it is linear.
