Multifunction: Also known as
A multifunction is also known as a many-valued function, a multiple-valued function or a multi-valued function.
On $\mathsf{Pr} \infty \mathsf{fWiki}$ the terse form multifunction is preferred.
When the number of values is known to be $n$, the multifunction can be referred to as an $n$-valued function.
