Relations and Functions

Note #1 FUNCTION We will discuss the characteristics of functions and definitions of domain and range. I will decide if a relation is a function or not.

Relations A relation is a set of ordered pairs. Let's take a look at a couple of examples:

4/13/2019 Homework: pg 49-50 1-8 and 20-26 Objective Agenda Recognize inputs/outputs of functions Determine if an expression is a function or relation Calculate the output of functions Bell Ringer New Notes Examples Homework: pg 49-50 1-8 and 20-26

Identify whether each list of ordered pair represents a function…Why or why not? {(5,4) (6,3) (7,2)}

Identify whether each list of ordered pair represents a function…Why or why not? {(4,5) (4,3) (5,2)}

Identify whether each list of ordered pair represents a function…Why or why not? {(5,4) (6,4) (7,4)}

Using POSITIVE integers, write two relations as a list of ordered pairs. One that is a function, one that is not. Graph. Function! NOT A FUNCTION! (-2, 2) (-1,1) (0,0) (1,1) (2,2) (0,0) (-1,1) (-2,2) (1,1) (-1,1)

Vocab Review Domain: Inputs of the function Range: Outputs

Consider a vending machine where inserting 25 cents dispenses 1 pencil, inserting 50 cents dispenses 2 pencils, and so forth up to and including 10 pencils. What is the domain in this situation? What is the range in this situation?
