A wrestling match has eliminations each round. The table below shows the number of wrestlers in each of the first 4 rounds of the tournament:
Round (x) 1 2 3 4
Wrestlers f(x) 64 32 18 9


Compute the average rate of change of f(x) from x = 1 to x = 4 and identify the meaning of that rate.
55; there were 55 fewer wrestlers between rounds 1 and 4
3; there were 3 rounds between rounds 1 and 4
negative fifty five over three; on average, there were 55 fewer players for every 3 rounds
negative three over fifty five; on average, there were 3 fewer players for every 55 rounds

Answer 1

                                          Net change of wrestlers       
Average rate of change = ---------------------------------
                                             number of rounds


                                           9 - 64  wrestlers        - 55 wrestlers
Average rate of change = ---------------------      = ------------------   
                                             4 rounds                    4 rounds
