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

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

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

01:24

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
