Multiplier curves are special function curves that you use to apply animated value displacements to other function curves.
When you edit keys and function curves, you apply localized changes to your animation at specific times. By applying a multiplier curve to the original track, you affect the entire range of the original animation.
A multiplier curve shifts the value of the original track up or down. At a given frame, the value of a multiplier curve is a scale factor applied to the value of the original function curve.
