How to graph a "free format" function
New to GeoGebra. I have tried to answer my own question looking at a number of videos, but either I find videos showing features from earlier version, of using an f(x)= definition type and I am getting really confused.
In the attached file and screenshot, you will see that I have entered some constant, destined to be used as sliders to simulate a final value called VPP In order to define VPP, I define an intermediate value called PT.
The calculations work fine (though I have not found a way to display the results as percentages and/or fractions yet), and dragging and dropping the sliders works fine, but for the life of me, I cannot get GeoGebra to simply graph VPP.
I must be missing something very simple so I apologise for the naive question.
Would you please let me know how to chart VPP? I can then introduce the sliders and simulate.
Thank you for your patience.
