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)negative fifty five over three; on average, there were 55 fewer players for every 3 rounds D)negative three over fifty five; on average, there were 3 fewer players for every 55 rounds

    average rate of change is the slope of the line use the points (1, 64) and (4, 9)

    (1*64)(4*9)= 2304? is right?

    slope = (change in y)/(change in x) sometimes referred to as slope = rise/run

    slope is x2-x1/ y2-y1

    so the points need to match for x and y slope = (64 - 9)/(1 - 4) what do you get

    so for your question its avg change = (change in wrestlers)/(change in rounds)

    well why not leave it as a fraction.... seeing some of the answer choices are fractions

    you have two points plug the x valule with the x vaule and y value with y

    so as an improper fraction.. what do you thing the avg change of slope would be..?

    well you had a decimal value avg change = (change in wrestlers)/(change in rounds) = (64 - 9)/(1 - 4)

    change in wrestlers 64 - 9 = avg change = ------------------------------------ -------------- change in rounds 1- 4 = what do you think the missing numbers in the fraction are..?

    great so you are looking at choices C or D so read the choices and decide which should be your answer

    but your answer choices don't contain a decimal... that's why I asked you to write it as an improper fraction.

    so you are saying the avg change is \[avg ~change = \frac{-3}{55}\] is that the same as you answer above \[Avg~ change = \frac{-55}{3}\]

    Which of the following options is an equivalent function to f(x) = 3(2)3x? f(x) = 3(8)x f(x) = 24x f(x) = 27(8)x f(x) = 3(8x)
