math problem

Answer 1

@AZ

Answer 2

so what is the domain?

from where to where does the x-values begin and end

Answer 3

-6 to 3

Answer 4

exactly so that's our domain!

what about the y-values

where does it go from and end at

Answer 5

-4 to -6

Answer 6

Good!

Now when we write it in interval notation

do you see how the two end points (-6, -4) and (3, -6)

how those two points are shaded? The circle dot on it is fully colored?

Answer 7

sorry i dont get it

Answer 8

az i dont get it

Answer 9

do you see how the circle is a solid blue color?

Answer 10

that means when we're writing it in interval notation

we have to use [ ]

instead of ( )

if it was a solid empty circle, then we would use ( and )
if it was infinity or negative infinity, we would use ( and )

Answer 11

yep

Answer 12

so basically the interval notation

for domain

use [ and ]

and domain is from -6 to 3

so [-6, 3]

Answer 13

what would the range be?

we have to use

[ and ]

and we're going from -4 to -6

so how would you write that

Answer 14

[-4, -6]

Answer 15

you got it! And that's your range

Answer 16

for my domain?

Answer 17

for your domain, you're going from -6 to 3

Answer 18

-4, to -6 is my range

Answer 19

yes

\(\color{#0cbb34}{\text{End of Quote}}\)

this would be your domain

and you already got the range

Answer 21

write the range as [-6, -4]

since -6 is a smaller number

Answer 22

so for domain and range

we always want to write it going from smaller to bigger

so -6 to 3

-6 to -4

- infinity to infinity

Answer 23

so since -6 is more negative, that is a smaller number

we'd list it first and then -4

Answer 24

thanks
