The function below shows the number of car owners f(t), in thousands, in a city in different years t: f(t) = 1.1t2 − 2.5t + 1.5the average rate of change of f(t) from t = 3 to t = 5 is thousand owners per year. answer for blank 1:

The average rate of change is :

Step-by-step explanation:

The number of car owners is modeled by the function;

, where t is the different number of years.

The average rate of change  of f(t)  from t=3 to t=5 is simply the slope of the secant line connecting:

(3, f(3)) and (5,f(5))

Which is given by:

Now, we substitute t=3 into the function to get;

We substitute t=5 into the function to get;

Therefore the average rate of change is :
