15.1: Discrete Functions
A More Formal Understanding of Functions
[edit | edit source]As you know, a function assigns an input to exactly one output. We defined the set of inputs as the function's domain and the set of outputs as its range.
To describe a function f with a domain X and a codomain Y, we use the notation
Discrete Functions
[edit | edit source]Up to this point, we have studied what are called continuous functions, which took on certain values on any given interval.
