WebIn most of the examples of set functions the input is a set of real numbers or points in R n and the output is a single real number, but they do not have to be. Some simple examples of set functions are: A function that assigns the number 0 to each set. We could call this the "zero function". A function that assigns the number 1 to a set if it ... WebWhat are Functions in Mathematics? A function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. Let A & B be any two non-empty sets; mapping from A to B will be a function only when every element in set A has one end, only one image in set B. Example:
