1/3 of an hour = 20 minutes
8 hours = 480 minutes
So to find the number of periods we divide 480 by 20. Answer is 24

Answer:
All real numbers
Step-by-step explanation:
To find the range of the function 
draw the graph of ths function (see attached diagram for details).
Since the base of the logarithm is 
the graph is increasing and passes through the point (1,0).
The domain of this function is
The range of this function is
or all real numbers.
