Can I do this thing that I don't even have a name for?

I honestly can't remember what this concept is called.

I want to know the name of the game object that called a particular function when onValueChanged happens.

For example, I name two sliders "LaunchAngle" and "RocketFuel", then set both of their OnValueChanged target in the inspector to the same function in a component I wrote.

From that component, can I tell which slider made the call?
