this looks cool. unfortunately i dont know how to do this i will contact someone who can tho.

#5 is incorrect. A number like x = 500 is not part of the domain (this is assuming your roller coaster doesn't go on forever to the right)

- jim_thompson5910

the range is also incorrect

What would it be, then? @jim_thompson5910

- jim_thompson5910

the furthest point to the left that your roller coaster starts at is (-14,0)
so x = -14 is the lowest x value allowed in the domain. Something like x = -15 is not allowed

- jim_thompson5910

I can't see where your coaster stops, but let's say it stops at (10,0)
x = 10 is the largest x can go

- jim_thompson5910

so if my assumption is correct, then the domain would be \(\Large -14 \le x \le 10\)

- jim_thompson5910

the range is handled the same way but for the y values of the points

- anonymous

Are you absolutely sure? So how would I write the range?

- jim_thompson5910

well if the coaster stops at (15,0) or something, then you just replace the 10 with 15

- jim_thompson5910

what is the highest point the coaster goes? the lowest point?

- anonymous

so then -14 <= x <= 15?

- Bossvideogamer21

sorry brook he aint coming

- jim_thompson5910

`so then -14 <= x <= 15?` yeah if the coaster stops at (15,0) or something

- Bossvideogamer21

and @MTALHAHASSAN2 isnt online neither is @carlyleukhardt

- anonymous

I just drew it like that, so I guess it can stop there, that's fine.

- jim_thompson5910

what is the highest point the coaster goes? the lowest point?

- Bossvideogamer21

Hey @brookeshearer99 ganeshie8 got me reinstated. cool right?

- Bossvideogamer21

i`ll talk to u laters brooke

- anonymous

(-9.5, 9) is the highest point and (2,0) is the lowest. @jim_thompson5910

- jim_thompson5910

so y = 9 is the largest y can get
y = 0 is the lowest y can be

- jim_thompson5910

the range is therefore `0 <= y <= 9`

- anonymous

okay, thanks!

- jim_thompson5910

you're welcome
