Several friends are standing near the middle of a long line waiting to enter a stadium to hear a concert. The friends have the following order in line: Sally, Traci, Susan, Kyle, Olga, Travis and Heather,
where Sally is ahead in line and Heather is behind. While waiting in the line, Kyle gets a call from his friend John, and John excitedly tells Kyle that he is the 9th person in line. Kyle replies that he has no idea what place in line he is, since the line is so long he can't see the front of it. Let f be the function that, to each positive integer n, assigns the name of the nth person in line. Let us agree to say that Kyle is in position k in line, since we have no idea what his exact position in line is. Answer the following questions.
