There are 32 teams participating in a single-elimination soccer tournament, in which only the winning teams from each round progress to the next round of the tournament. the graph shows the number of teams, f(x), that are still in the tournament after x rounds have been completed. determine the domain and range of this function. a. d = [0, 5] and r = [0, 32] b. d = {0, 1, 2, 3, 4, 5} and r = {1, 2, 4, 8, 16, 32} c. d = {0, 1, 2, 3, 4, 5, 6, 7} and r = {0.5, 0.25, 1, 2, 4, 8, 16, 32} d. d = {1, 2, 4, 8, 16, 32} and r = {0, 1, 2, 3, 4, 5}
