When working with functions (of all types), the average rate of change is expressed using function notation:


(f(b)-f(a))/(b-a).

For the interval from x=7 to x=8,

1. find f(7) and f(8):


  • f(7)=729\cdot 3=2187;

  • f(8)=2187\cdot 3=6561;

2. use given formula:


(f(8)-f(7))/(8-7)=(6561-2187)/(8-7)=4374.

Answer: the average rate of change for the interval from x=7 to x=8 is 4374.
