Amit and Rahul decided to ride a new coaster. While waiting in line, Rahul notices that part of this coaster resembles the graph of a polynomial function that they have been studying in their maths class. (i) The brochure for the coaster says that, for the first 10 seconds of the ride, the height of the coaster can be determined by h (t) = 0.3t3 – 5t2 + 21t, where “t” is the time in seconds and “h” is the height in feet. Classify this polynomial by degree and by number of terms. (ii) Find the height of the coaster at t = 0 seconds. Explain why this answer makes sense. (iii) Find the height of the coaster 9 seconds after the ride begins. Explain how you found the answer. Or, Graph the polynomial function for the height of the roller coaster on the coordinate plane at the right. From the graph, find the maximum height of the roller coaster
