@dude 3a. Domain:

woolyfrog:

how do I get the domain and range of the rainbow

dude:

Okay so we know that the domain of parabolas (the rainbow) are from infinity to negative infinity

woolyfrog:

brb

woolyfrog:

I'm back and hai okay

woolyfrog:

I dont understand

woolyfrog:

help

dude:

Which part do you not understand

woolyfrog:

all of it

woolyfrog:

I don't know the domain

woolyfrog:

what should I write

dude:

_oh ok_ Do you know what Domain is?

woolyfrog:

no

dude:

Oh boy. Ok the domain is the x values

woolyfrog:

hai ok

dude:

Ok the domain explains how far the graph goes on for horizontally

woolyfrog:

Hai ok

dude:

Ok does the first part make sense now?

woolyfrog:

yes I understand more now but what is range

dude:

Range is the y value (How high and how low that graph goes)

woolyfrog:

so how high the line goes?

dude:

The equation, yes (Not all equations are lines)

woolyfrog:

is the domain the x value

dude:

Yeah

woolyfrog:

I wrote everything down

woolyfrog:

What are the x and y intercepts of the rainbow? Explain what each intercept represents

dude:

I wrote it in Anime's post

woolyfrog:

What are the solution(s)? Explain why in complete sentences.

woolyfrog:

when do they both touch

dude:

This was answered in the post <_<

woolyfrog:

(-3,27) and (2,32) are the solutions for me too

dude:

Oh right different equations

dude:

My bad Your solutions were (-6,0) and (0,32)

woolyfrog:

thank you so much!

woolyfrog:

that is the solution because that is when the rainbow and airplane both are in the same height?
