anonymous one year ago HELP!! HAVE TO FINISH LESSON NOW!! 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. A)55;there were 55 fewer wrestlers between rounds 1 and 4 B)3;there were 3 rounds between rounds 1 and 4 C)-55/3;on average,there were 55 fewer players for every 3 rounds D)-3/55;on average,there were 3 fewer players for every 55 rounds

$aroc=\frac{ f(b)-f(a) }{ b-a }$ you want the average rate of change from 1 to 4, so let a = 1 and b = 4 $aroc=\frac{ f(4)-f(1) }{ 4-1 }$
