For this Critical Thinking Assignment, you will be creating your own real-world scenario and exploring the meaning of differentiation of exponential functions in that context.
Part I: Complete the following steps:
- Select a real-world scenario that can be modeled by an exponential function and define the function F(x) based on your scenario. (Ex.: Suppose that F(x) computes the rabbit population on a game reserve that doubles every 6 months. Suppose there were 120 rabbits initially.)
- Write a mathematical expression for F(x).
- Find the domain and range of F(x).
- Find F(x) and F ‘(x) at any point.
- Find all x values for which F ‘(x) = 0.
Part II: Based on your work in Part I, discuss the following:
- Discuss if your function F(x) is differentiable and why. If it is not differentiable, select another function that is and discuss the change you made.
- Discuss the domain and range of F(x) and why they make sense in the context of your problem.
- Discuss the physical meaning of F(x) and F ‘(x) at a point in the context of your problem.
- Discuss what it means for F ‘(x) = 0 in the context of your problem.
- Reflect on any adjustments you had to make to your original problem context and discuss what characteristics of a real-world context make it a valid choice for applying differentiation concepts to it.
- Provide at least two other real-world situations where differentiation can be applied and respond to the following:
- What common characteristics do the real-world scenarios you chose share?
- What did you look for in the way that the real-world scenario can be modeled?
- Discuss the criteria for selecting a real-world scenario that would change if you were seeking to model it with a logarithmic function instead. What key similarities and differences would you find?
