I'm having trouble coming up with an equation to graph this. I'm trying to create a visual representation of a product for an Excel graph or a calculator but can't figure out how to go about it.
This example (although poorly drawn) is similar to what I'm looking for. The values in this would be:
The reason for having 3 variables is Z is where I need the curve to start, Y is the max value for the curve and X is how long the curve will last until coming back down to the original value. Another variable I didn't think of was I need it to be able to start at a value of 50,000 and not 0.
I'm not even sure where to start... any help would be appreciated. Thanks!
