  • 1. A retirement account is opened with an initial deposit of $8,500 and earns 8.12% interest compounded monthly. What will the account be worth in 20 years? What if the deposit was calculated using simple interest? Could you see the situation in a graph? From what point one is better than the other? 1. Graph the function f (x) = 5 (0.5)-x and its reflection about the line y=x on the same axis, and give the x-intercept of the reflection. Prove that ax =exlna. [Suggestion: type y = 5(0.5-x) {- ...

  • Reflect on the concept of exponential and logarithm functions. What concepts (only the names) did you need to accommodate these new concepts in your mind? What are the simplest exponential and logarithmic functions with base b ≠ 1 you can imagine? In your day to day, is there any occurring fact that can be interpreted as exponential or logarithmic functions? What strategy are you using to get the graph of exponential or logarithmic functions?

  • What happens if we graph both f and f -1 on the same set of axes, using the x-axis for the input to both f and f -1 ? Type y = x3 {-2 < x < 2}, y = x 1/3 {–2 < x < 2}, and y = x {–2 < x < 2}, and describe the relationship between the three curves. Then post your own example discussing the difficulty of graph both f and f -1 on the same set of axes. Suppose f: R →R is a function from the set of real numbers to the same set with f(x) =x+1. We write f 2 to repre...
