In 2009 the number of vehicle sales in the United States was 10,002 thousand and in 2013 it was 17,884 thousand. a. [3 pts] Determine the average rate of change (slope) from 2009 to 2013.b.

1970.5 thousand

Step-by-step explanation:

Given

Vehicle sales in 2009 = 10,002 thousand

Vehicle sales in 2013 = 17,884 thousand

Required

Determine the average rate of change;

From the given parameters, it can be seen that the number of vehicles is a function of year

Let x represent the years and y represent the number of vehicles;

Such that;

The rate of change is calculate as follows;

Hence, the average rate of change is 1970.5 thousand

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
