Answer 1

@pooja195

Answer 2

any ideas?

Answer 3

hint: what are the x-values that the graph covers?

Answer 4

the x values are -3 and 4 @Vocaloid

Answer 5

not quite

Answer 6

what I meant was, what x-values can be found on the graph?

Answer 7

are there any x-values that the graph does not have?

Answer 8

umm i dont know

Answer 9

domain is the list of all possible x values on the graph

Answer 10

do you see how the graph has every possible x-value on it?

Answer 11

I could pick any x-value, and find the matching y-value on the graph

Answer 12

make sense?

Answer 13

i guess zero wouldnt be one of them

Answer 14

really?

Answer 15

look at the graph where x = 0

do you see a matching y-value?

Answer 16

im reading the graph like a regular x and y axis

Answer 17

of course

Answer 18

when x= 0, what is y?

Answer 19

Answer 20

nope
