For the function
c.
Can the model be used to predict the percent of households with wireless-only telephone service in
c.
Answer to Problem 80E
YES.
Explanation of Solution
Calculation:
To state whether the model can be used or not for the upcoming years
The answer is yes, the model function can also be used for the upcoming years in
Hence, as it is a logarithmic function so with the increase in the value of
