Set 17: Exponential Functions

Choice A is correct. Choice A is the correct answer. Exponential growth increases with $x$. 1. Base: $1.1> 1$ means the function is growing. 2. Comparison: As $x$ increases, $(1.1)^x$ increases. 3. Conclusion: $f(10) > f(5)$ since $10> 5$. Strategic Tip: For growth functions ($b > 1$), larger $x$ gives larger $y$. Choice B is incorrect because the function is increasing. Choice C is incorrect because different inputs give different outputs. Choice D is incorrect because we can determine this from the growth property.
