Teaching Students About the Definition of a Function

Teaching students about the definition of a function is a fundamental aspect of mathematics education. Understanding functions is essential for students who want to pursue careers in fields such as engineering, physics, economics, and computer science. So, what is a function? A function can be defined as a set of ordered pairs in which each element in the domain (the set of all input values) corresponds to exactly one element in the range (the set of all output values). In simpler terms, a function is a rule that assigns each input value a unique output value. One way to introduce... [Read more...]
