Best ResponseYou've already chosen the best response.0The function below shows the number of car owners f(t), in thousands, in a city in different years t: f(t) = 0.25t2 − 0.5t + 3.5 The average rate of change of f(t) from t = 2 to t = 6 is ______ thousand owners per year.

Best ResponseYou've already chosen the best response.0the average rate of change is like the slope of a best fit line slope of a line is change in y / corresponding change in x = y2  y1 find the y value when x = 6 this is y2 find the y value when x = 2 this is y1 the change in x from 6 to 2 this is the same thing done above by @Vocaloid

Best ResponseYou've already chosen the best response.0oops a typo in the function should be \[f(t) = 0.25t^20.5t+3.5\]

Best ResponseYou've already chosen the best response.0What vocaloid found was the total change during the total period from t=2 to t=6, but the question asked for average rate of change from period t=2 to t=6.
