A) 30 
B) 2.5 
C) 10 
D) None of the above

Quizplus · Accepted Answer

To find the average rate of change, we need to divide the change in the function value by the change in the input. From the graph, we can see that the function value changes from 25 to 30, which is an increase of 5, and the input changes from 10 to 12, which is an increase of 2. Therefore, the average rate of change is 5/2, which simplifies to 2.5.
