For this case we have the following function:
 f (x) = 0.01 * (2) ^ x

 By definition, the average rate of change is given by:
 AVR =  \frac{f(x2) - f(x1)}{x2 - x1}
 We evaluate the function for the given values:
 For x = 7:
 f (7) = 0.01 * (2) ^ 7

f (7) = 1.28
 For x = 14:
 f (14) = 0.01 * (2) ^ {14}  f (14) = 163.84
 Then, replacing values we have:
 AVR = \frac{163.84 - 1.28}{14 - 7}
 AVR = 23.22
 Answer:
 
the average rate of change from x = 7 to x = 14 is:
