#

Okay so the domain is the x axis and the range is the y

#

So let's focus on the range

#

How high does the first one go

raven abyss Sep 3, 2024, 5:18 AM

#

1

coral roost Sep 3, 2024, 5:18 AM

#

How low does it go?

raven abyss Sep 3, 2024, 5:18 AM

#

-infinity?

coral roost Sep 3, 2024, 5:18 AM

#

Exactly

#

So the range is from 1 to negative infinity

#

Use whatever notation your teacher said to use

#

Now for the domain

#

How far does it go left?

raven abyss Sep 3, 2024, 5:19 AM

#

1

coral roost Sep 3, 2024, 5:19 AM

#

No think about it

#

It continues off the page

#

Forever and ever

raven abyss Sep 3, 2024, 5:20 AM

#

so -infinity

coral roost Sep 3, 2024, 5:20 AM

#

Yep and to the right would be

raven abyss Sep 3, 2024, 5:20 AM

#

-inf again..?

coral roost Sep 3, 2024, 5:20 AM

#

Not negative because you are going in a positive direction

#

But infinity

raven abyss Sep 3, 2024, 5:20 AM

#

okay

coral roost Sep 3, 2024, 5:21 AM

#

And just looking at it what's the value of f(0)

#

Or in other words where does the x axis and the function cross

raven abyss Sep 3, 2024, 5:22 AM

#

so for #3 it would be.. [4, -inf) for range and then [-4, 4] for domain?

raven abyss Sep 3, 2024, 5:23 AM

#

coral roost Or in other words where does the x axis and the function cross

I dont know 😭

coral roost Sep 3, 2024, 5:23 AM

Here I need to sleep @inner willow can you finish

#

It's late for me and I have to get up at 5 am

frail pasture Sep 3, 2024, 5:23 AM

#

how'd you do the other ones

inner willow Sep 3, 2024, 5:24 AM

#

alright

frail pasture Sep 3, 2024, 5:24 AM

#

it's the same thing as the other ones

inner willow Sep 3, 2024, 5:25 AM

#

raven abyss I need help. I have no idea what I'm supposed to do.. I only need 1 and 3

1 has domain (-infty,infty) and range (-infty,1] and 3 has domain [-4,4] and range [0,4]

raven abyss Sep 3, 2024, 5:26 AM

#

Okay but I also need to find f(0)

inner willow Sep 3, 2024, 5:27 AM

#

ah, yeah, that’s when x = 0 so it’s the value of f at the y axis

#

1 is 1 and 3 is 4

raven abyss Sep 3, 2024, 5:27 AM

#

how tho

frail pasture Sep 3, 2024, 5:27 AM

#

inner willow ah, yeah, that’s when x = 0 so it’s the value of f at the y axis

y

raven abyss Sep 3, 2024, 5:29 AM

#

I need the explanation pls ;-;

inner willow Sep 3, 2024, 5:30 AM

#

frail pasture y

ye thx

inner willow Sep 3, 2024, 5:31 AM

#

raven abyss I need the explanation pls ;-;

Do you know how to read a Cartesian plane chart or whatever they call it

summer jungleBOT Sep 3, 2024, 5:31 AM

#

@inner willow has given 1 rep to @frail pasture

inner willow Sep 3, 2024, 5:31 AM

#

the vertical direction is canonically “y” and the horizontal direction is “x” (rightwards)

#

f(0) is the y value at x = 0

raven abyss Sep 3, 2024, 5:32 AM

#

gotcha ok
