Functions August 29, 2016 By Deryn Susman Function: a rule “f” which associates to every input “x” (in the domain) a unique output “f(x)” Input →rule →output Domain: the collection of all possible inputs; every function needs a domain “In thiscourse, we will always assumethatfcomes with its maximal domain.” Variables: Vessels which we can assign value Mostcommon: x, y, z, t Restrictions on Domain 1. Denominators can never be zero. 2. Expressions under a radical ( √ ) must be ≥ 0 Inequalities and Intervals Defined: Two numbers “a” and “b,” either a = b or a
