2. The function f(SID) takes as an input the student ID number of a student in this room, and returns his or her full name. Is f(SID) invertible? (That is, does it have an inverse function?) If so, what would this inverse function do? If not, why not? 3. The function (SID) takes a UC Merced student's ID number, and returns his or her height, to the nearest inch. Is h(SID) invertible? If so, what would this inverse function do?...
