A volleyball playoff competition has eliminations each round. The table below shows the number of teams in each round of the tournament:

Round (x) 1 2 3 4

Teams f(x) 16 8 4 2

Compute the average rate of change of f(x) from x = 1 to x = 4 and identify the meaning of that rate.

-3/14; on average, there were 3 fewer teams every 14 rounds

-14/3; on average, there were 14 fewer teams every 3 rounds

3; there were three rounds between rounds 1 and 4

14; there were 14 fewer teams between round 1 and 4
