Functions 1 Functions A function f from a set A to a set B is an assignment of exactly one element of B to each element of A. We write f(a) = b if b is the unique element of B assigned by the function f to the element a of A. If f is a function from A to B‚ we write f: AB (note: Here‚ ““ has nothing to do with if… then) 2 Functions If f(A)=B‚ we say that A is the domain of f If f(a) = b‚ we say that b is the image of a. The range of f(A)=B is the set of all images of elements of A. We say that
