1. The brochure for the coaster says that, for the first 10 seconds of the ride, the height of the coaster can be determined by  , where t is the time in seconds and h is the height in feet. Classify this polynomial by degree and by number of terms. 


This polynomial is a cubic trinomial

2. Graph the polynomial function for the height of the roller coaster
    on the coordinate plane at the right. 
									           25
								
3. Find the height of the coaster at t = 0 seconds. 
    Explain why this answer makes sense. 
     
     h(0)= 0 									          2        4	      6    8
    This value means that the ride starts on the ground
											
4. Find the height of the coaster 9 seconds after the ride begins. Explain how you found the answer.

h(9) = 2.7 feet       the answer is found by substituting 9 for each x in the equation


5. Evaluate h(60). Does this answer make sense? Identify practical (valid real life) domain of the ride for this model. CLEARLY EXPLAIN your reasoning.  (Hint.: Mt. Everest is 29,028 feet tall.)

    h(60) = 48,060 feet       

  the answer is not reasonable, because it is too high for a roller coaster ride. 

  On the graph, after 10 seconds, ride keeps increasing in height to infinity, therefore practicel domain is no more than D: 0< x < 12

but that all depends on how you did your coaster
