Sorry And here's your shmoop du jour brought to you

00:04

by data collect the whole set Our staff's majors were

00:10

just rolling in the aisles on them All right what's

00:12

the domain of this data set And is this data

00:15

set of function Well here potential answers remained Pain remains

00:19

main ship All right so a little cab testing here

00:23

First of all the problem wants to know if we

00:25

can tell a domain from a range as in home

00:29

home on the unfortunately we don't have to be able

00:32

to tell either of them from a hole in the

00:33

ground which is good because that hole is the pits

00:37

Quite simply the domain of the data set is the

00:40

collection of x values or the input While the range

00:44

is the collection of why values or the output just

00:48

remember the domain comes before range alphabetically Input comes before

00:52

output and food comes before Well never mind Just ex

00:56

comes before Why All right they all match up or

00:59

whatever helps you to remember huh So we won't push

01:02

our demonic devices on you too hard let's Just go

01:05

Okay well if the domain is the set of x

01:07

values or in this case three five six eight and

01:10

a then we cross off options Be indeed it's got

01:13

to be between a and c the only choices that

01:16

list the correct data set Alright now part two is

01:19

the set of function Well unfortunately definition of a function

01:24

says that every input can have only one output right

01:28

one toe one since eight gives us both seventeen and

01:32

twenty three here were functional isthe story answer has to

01:35

be c which comes before d alphabetically that's not a

01:39

demonic device We just thought we'd mention it but yeah

01:41

it's C
