    #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)

    the range is also incorrect

    What would it be, then? @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

    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

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

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

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

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

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

    so then -14 <= x <= 15?

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

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

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

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

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