Here is a little interactive R / Shiny app I made to help visualize discount functions.
To run it, download the code and load up
app_hyperbolic/app.R in RStudio, then click the "run app" Button. You should then see something like this.
Note that you can drag and drop the graphs (onto your desktop for example) in order to include them in any of your own documents.
