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
