3. Graph this polynomial on the grid at right by making table of values and plotting points. h (t ) t (sec) h(t) feet 0 1 2 3 Height 4 Time 5 6 100 8 14. What is the domain of this model? Is it only valid from t = 0 to t = 8? Why or why not? 15. What happens after 8 sec? Explain. 16. At what time(s) is this coaster's height is about 50 feet? Clearly explain how you found your answer. 17. Locate all real zeros of this function. Clearly interpret the real-world meaning of these zeros. 18. Would you ride on this coaster? Why or why not? Explain logically
