Document Summary
Book reading - 0. 1: functions and graphs from a to a set b is an assignment f f of the domain set a exactly one element that associates to of f (x) Functions: a function each element the codomain, or target, set b. Notation: f : a b x: this notation represent a function set a and target set b, pronounced as " from a to b" f, simple note: x i ndependant variable. Domain and range of function: if is a function between unspecified subsets of be the largest subset of. Domain for which is defined: (f ) = {x r | f (x) is def ined} R f f: the range of such a function is the set of all possible outputs: , then we will take the domain of. Range(f ) = {y r | there is some x domain (f ) f or which f (x) = y}
