well give medals but please explain and help ! PLZZ help
A chess competition has eliminations each round. The table below shows the number of players in each of the first 5 rounds of the tournament:
Round (x) 1 2 3 4 5
Players f(x) 256 128 64 32 16
Compute the average rate of change of f(x) from x = 1 to x = 5 and identify the meaning of that rate.
−60; on average, there was a loss of 60 each round
−240; on average, there was a loss of 240 each round
4; there were 4 rounds between rounds 1 and 5
240; there were 240 fewer players between rounds 1 and 5

Best ResponseYou've already chosen the best response.1they ask about average rate of change that means find the change in y divided by the change in x (which by the way, is also the slope between 2 points)

Best ResponseYou've already chosen the best response.1average change from x = 1 to x = 5 write the (x,y) pairs for when x=1 (y i.e. f(x) is 256) and when x=5 (and y is 16, according to the table) your two points are (1,256) and (5,16) find the "slope" between those two points.

Best ResponseYou've already chosen the best response.0Okay and i would use average rate of change to find it @phi

Best ResponseYou've already chosen the best response.1actually, I think of it the other way round: find the slope and that is the average rate of change. finding the slope is always change in y divided by change in x can you do that ?

Best ResponseYou've already chosen the best response.0okay so it would be 16/5 and 256/1 ?

Best ResponseYou've already chosen the best response.1from (1,256) and (5,16) pick out the y values: 256 16 that is the change in y then do the x's (in the same order) 15 is the change in x

Best ResponseYou've already chosen the best response.1yes, now divide: change in y divided by change in x
