WebFunctions. We can define a function as a special relation which maps each element of set A with one and only one element of set B. Both the sets A and B must be non-empty. A function defines a particular output for a particular input. Hence, f: A → B is a function such that for a ∈ A there is a unique element b ∈ B such that (a, b) ∈ f Web2 days ago · Excel 365 VBA function works with numbers as parameters, but not references #ERROR.
