Problem: Suppose that an old hospital building leaks N20 (nitrous oxide} into the air. It leaks continuously (all the time). but not at a constant rate. Suppose AH] gives the total volume of N20 [measured in cubic metres) that the hosPital has leaked since midnight on 1 March, 2023, which is t = 0. Time. at, is measured in weeks and the domain of Alit} is D = [0. DC). The table below shows some select values of AH): t:|123456789101112 ----------I 1. (1 mark} How much N20 did the hospital leak from midnight on 15th March 2023 until midnight on 5th April 2023? Show your work. 2. (a) (2 marks) ls Ali] an invertible function? Explain. [b] (1 mark} ls A_1{10.] defined? If yes. find it's value [either exactly or approximately} and explain with a sentence what it represents. If not. explain why not. (c) (1 mark) Is A_1{10.8} defined? Explain
