Answer 2

@arabpride

Answer 3

can you fan a sista back

Answer 4

Well, lemme explain...
domain = x-value
range = y-value

In a function, you're \(range\) can be repeated, whereas your range cannot be repeated, and still be considered a function

Answer 5

its not a range right

Answer 6

I mean its not a function

Answer 7

So here, you your domain values are -5, -1, 3, and 8
are any of those numbers repeated?

Answer 8

no

Answer 9

Therefore, that set of solutions is a function
(the y-value is repeated, but that doesn't matter in determining whether or not a set is a function).

Answer 10

so for the answer part I would write yes because there is no repeating number

Answer 11

@arabpride

Answer 12

because there is not repeating DOMAIN value**

Answer 13

no*

Answer 14

but this is a function right

Answer 15

Yep

Answer 16

okay now I have to state the domain and range

Answer 17

Well like I said, the domain is the x-value and the range is y-value (x, y)

Answer 18

it goes in least to greatest

Answer 19

I know but I need help with putting the number in order

Answer 20

Just imagine a number line!

Answer 21

negative values on the left, positive values on the right

Answer 22

for the range would be -5,-1,3,8

Answer 23

no, that would be your domain.

Answer 24

I mean domain

Answer 25

lol, yes

Answer 26

then the range would be -2,-6,1,1

Answer 27

from least to greatest though? -6 is less than -2
and since the number 1 is repeated twice, you don't have to write it two times, just once is fine

Answer 28

no my teacher is picky tho

Answer 29

what then my range is -6,-2,1

Answer 30

@arabpride

Answer 31

Alrighty then

Answer 32

its -6,-2 and 1 for the range then.......

Answer 33

That's it
