Having plenty of free time to spare, the TAs decide to compete in their own video game competition. Let A be the set of TAs, and B be the set of video games in the competition. Before the awards ceremony, the TAs decide to model the competition using some functions. Let function f: A---> B map each TA to her favorite video game that she competed in. Let function g: B\--> A map each video game to the TA who came first in that video game. The TAs notice that for any video game, the TA that came first in that video game also has that video game as her favorite. That is, for all y in B f(g(y)) = y. Knowing this, prove that the number of TAs is greater than or equal to the number of video games. Having plenty of free time to spare, the TAs decide to compete in their own video game competition.
