Best ResponseYou've already chosen the best response.0The function below shows the number of students of a school who enrolled for ballet classes. Let f(x) represent the total number of students who enrolled for the classes after x years: f(x) = 12(1.06)x The average rate of change in the number of students who enrolled for ballet classes from the third to the fifth year is ________students per year.

Best ResponseYou've already chosen the best response.1can you double check if there are any typoes in the function i think the "x" should be in the exponent

Best ResponseYou've already chosen the best response.1Okay great! i hope you see the difference between \(12(1.06)x\) and \(12(1.06)^x\)

Best ResponseYou've already chosen the best response.0Is this how you do the graph to find the difference? f(x) = 12(1.06)^x 1 12.72 2 13.47

Best ResponseYou've already chosen the best response.1you need to find the points when x = 3 and x = 5 not when x = 1 and x = 2

Best ResponseYou've already chosen the best response.1okay, look at the highlighted points 1 12.72 2 13.48 `3 14.29` 4 15.14 `5 16.05`

Best ResponseYou've already chosen the best response.1we need only them because we're asked to find the average rate of change between years 3 and 5

Best ResponseYou've already chosen the best response.1remember the slope formula ?

Best ResponseYou've already chosen the best response.0so i would do mean to find the difference? 14.29+15.14+16.05=45.48 45.48/3= 15.16 difference?

Best ResponseYou've already chosen the best response.1(3, 14.29) and (5, 16.05) slope = (16.05  14.29) / (53) = ?

Best ResponseYou've already chosen the best response.1Looks good! 0.88 is the average rate of change between years 3 and 5
