PART C: THINKING AND INQUIRY 5. A person drops a water balloon from a 180 m tall building. After t seconds, the balloon has fallen a height of h meters, where h(t)=180-512. Show all work and state all conclusions. [7 marks] a) What is the average speed of the balloon between 1 and 2 seconds. b) What will the velocity of the balloon be at 2 seconds? 6. Determine if the following function is continuous at x = 3. [4 marks] f ( x) = -x, ifx 53 1 - x, if x > 3
