Answer 1

@sammixboo

Answer 2

I don't think you can Sir.

Answer 3

So you can't find domain and range without points? What if there's a line?

Answer 4

Maybe???

Answer 5

wym like without a graph?

Answer 6

There's a graph, just no points

Answer 7

You can use this for reference

Answer 8

You would multiply

Answer 9

your supposed to find x and y then

Answer 10

From point a to the diagnal pont.

Answer 11

How exactly would I do that?

Answer 12

from the end of the lines

Answer 13

like the one touches the lines i think

Answer 14

Yes

Answer 15

so the actual intercept is the domain and range?

Answer 16

i think thats how you do it

Answer 17

Alright, thank you tet o;

Answer 18

Np

Answer 19

So, domain is 6, and range is 3?

Answer 23

Domain is how far left and right the graph goes
Range is how far up and down the graph goes

Answer 24

So for this graph, given that it has arrows showing that it’s continuous on both sides we can make the domain and range

Domain: (-♾,+♾)
Range: (-♾,+♾)

Answer 25

Now if it was given a stopping point (e.g. the line ended in Q3 (bottom left), at point (-4,-3), it would look like this

Domain: (-4,♾)
Range: (-3,♾)

Answer 26

Thanks Extrinix o;

Answer 27
