During dispatch, the generic function selects the most specific applicable method from the available overloads.

To calculate the average rating for each product, use an aggregate function that processes multiple rows at once.

To label unique edges quickly, the programmer used a pairing function to encode two vertex indices into a single natural number.

Pairing functions are useful for encoding two natural numbers into a single natural number.

The textbook includes an example of a surjective function that maps the real numbers onto the open interval (0,1).

The professor asked us to compute several function values for the given domain points.

During the seminar, the students constructed several onto functions to illustrate how every element of the codomain is achieved.

Many proofs in algebra rely on surjective functions to transfer structure between sets.

An onto function ensures every element in the codomain has a preimage.

Concerns about gains-of-function have led to stricter regulations.
