The sample function produced a representative set of observations from the population for the analysis.

In many algebra problems, a symmetric function of the variables simplifies the computation because swapping arguments doesn't change its value.

To model the projectile's path, the engineer approximated its height with a quadratic function.

To approximate the integral, we first replace the function by a simple function that takes only finitely many complex values.

In propositional logic, each connective defines a truth function that maps the truth values of its inputs to a truth value for the whole formula.

To compute the gradient, first identify a scalar function defined on the vector space.

To test the algorithm's robustness, we implemented a random function that maps each input to a uniformly selected value from the domain.

The work function of the metal determines whether electrons will be emitted under ultraviolet light.
