#

Alright so which of these do u need help with

woeful gust
#

All 😭😭

tribal sleet
#

No worries

#

Alright let's start with #1

woeful gust
#

Okk

tribal sleet
#

h(t) shows the height

#

What time was the ball launched?

#

Or rather

#

What time must have it been launched

woeful gust
#

Hm it says t seconds

#

Is that what I need to figure out?

tribal sleet
#

Well its not a matter of figuring it out

#

As much as it is just knowing

#

Any physicist always starts their experiment at t=0 seconds

#

So plug 0 in for t

#

And that will give the height at launch

woeful gust
#

So h(t) is the height of the projectile 0 seconds after launch?

tribal sleet
#

Yep

#

Well

#

No

#

h(0) is the height 0 seconds after launch

woeful gust
#

Oh yeah I understand

#

So the answer is ht but I replace t with a 0

tribal sleet
#

Functions are awesome bc they let us take a value from one type of thing and transform it into another type

woeful gust
#

Wow thankss that has helped me understand the whole concept more

tribal sleet
#

What answer did u get btw?

woeful gust
#

Uhh I think I’m confused 😭

#

Do I Times 4.9 with (0-3)

tribal sleet

#

Sorry for the delayed response

#

The one thing I really need help understanding is how to figure out the domain and codomain in graphs

tribal sleet
#

ill help in just a moment then

woeful gust
tribal sleet
#

hopefully youre still available

woeful gust
woeful gust
#

I want to understand how how to find out the domain and
Codomain in graphs

#

For example these ones

IMG_9985.png
#

My friend already did the exercise but I didn’t understand it

#

@tribal sleet

tribal sleet
#

well just remember

#

the domain is all the input values that work

#

and the codomain are the output values

#

so if there is a filled in dot at a point, its included

#

even if theres a not filled in dot above or below it

#

@woeful gust does this make sense?

woeful gust
#

No I don’t understand

#

What’s the difference between output and input values

tribal sleet
#

input values are on the x axis

#

output are on the y

#

so if i have some function f(x)

#

the x is the input

#

f(x) is the output

woeful gust
#

Ohh ok

tribal sleet
#

also remember

#

that () is open

#

and [] is closed

#

open means it doesnt include the end value

woeful gust
#

Okk

tribal sleet
#

closed means it does

woeful gust
#

Here in Brazil we do ] closed

#

[ open

woeful gust
#

Could you accept my friend request plss I think I’ll need your help in the future

tribal sleet
tribal sleet
#

if [ is on the left its closed

#

but if its ] on the right its open

woeful gust
#

For example an answer to an equation could be [-4,+5,7[

tribal sleet
#

ive never seen that before

#

im in the US tho

woeful gust
#

Oh ok

#

We also don’t use 2.4 decimal points or anything like that

#

We use commas ,

tribal sleet
#

ah

#

would you say 100 million is 100.000.000 then

woeful gust
#

2,4

#

100,000,000

tribal sleet
#

ohh

#

so no commas at all

woeful gust
#

Like no dots

#

We use this instead of”,”

tribal sleet
#

oh yeah sorry

#

thats what i meant

woeful gust
#

Yeahh

#

I think imma need help in like in one hour an 30 minutes 😭😭

#
