i need help!! domain and range!!

[silent dust]

do you know what domain and range refers to?

[plush otter]

nope :))

[silent dust]

ok

domain basically refers to the x-values

for which x values is the function defined

for example

x = -4

it is not defined

[plush otter]

ohh

[silent dust]

defined in terms of

that for some x value we have a y value

for example

for x = 0

it is defined

y = 4

so basically

look for when the function begins

from the left

and go along it

until you reach endpoint

that would be your domain

in terms of x

[plush otter]

oooohh

[silent dust]

does that help, any clues?

[plush otter]

yeah it does, tysm!

[silent dust]

hmm ok

about the range

it's basically what possible y values can be attained

most of the times it's just and interval from lowest to highest y value

if the function has no loops

[plush otter]

no loops?
