Question

The annual revenue for Apple in 2008 was $37.5 billion and in 2013 the annual revenue was $170.9 billion.

What was the increase in annual revenue between 2008 and 2013?

On average, how fast was the revenue growing each year?

To calculate your answer to the previous question you did the following calculation:

(170.9 37.5/2013-2018)

What does this calculation remind you of? _____________

You have just calculated an AVERAGE RATE OF CHANGE (AROC). The Average Rate of Change (AROC) of f(x) over the interval [a, b] is the slope of the line between (a, f(a) ) and (b, f(b) ).

AROC= (F(B)-F(A)/(B-A))

Write a sentence that interprets the AROC that you just found.
