Function Relationship

Determine if each relation is a function. For each function, state the domain and range.

Question 1

Father...............Daughter

Bob------------------>Beth & Diane
John---------------->Linda
Chuck-------------->Marcia

As the table shows, Bob is matched with two different daughters.
I say this is not a function.

Do you agree?

Question 2

Level of Education...............Average Income

Less than 9th grade------------>$18k
9th to 12th grade---------------->$23k
H. S. Graduate-------------------->$36k
Some College--------------------->$45k
College Graduate--------------->$67k

I say this table shows a function.

Domain = Level of Education List

Range = Average Income List

Do you agree?

Setting up a table helps to understand the idea of what a function is.
