I have a hunch that f is in MILLIONS
f(t)= (1/2)(1.498) t^2 + 1.626 t + c
to find c put in year 2
8.893 = (1/2)(1.498) (4) + 1.626 (2) + c
The approximate rate of change in the number of subscribers to wireless service
is given by f’(t) = 1.498t + 1.626, where t represents the number of years since 1990. In 1992
(t = 2) there were approximately 8.893 million subscribers.
Find the function that gives the total number of wireless service subscribers in year t.
