Question 1150552
Build a roller coaster 
Create a polynomial equation and graph based off the following 
- it must have different phases: ground level, sea level, below sea level, and above ground 
-Max of 1 minute 
-it must also have 4 turns 
-must start and end at ground level
=====================
Not clear.
Is below ground lower than below sea level?
"4 turns" plus the changes in elevation implies 3-space.  Is that expected?
