Consider functions where the domain is 1.2. 10) and the range is (a, b). (a) how many of these functions are there? (hint: a function is considered different if at least one of its inputs is assigned to a different output. how many different outputs are possible for the input 1? what about for the input 27] (b) how many of these functions are onto? (hint: take your answer to part (a), and subtract the number of functions that are not onto.
