The sales of digital cameras (in millions of units) in year t is given by the function
f(t) = 3.06t + 6.84 (0 ≤ t ≤ 3)
where t = 0 corresponds to the end of 2001. over that same period, the sales of film cameras (in millions of units) is given by
g(t) = −1.85t + 16.48 (0 ≤ t ≤ 3).
(a) show that more film cameras than digital cameras were sold in 2001.
digital cameras
million
film cameras
million
(b) when did the sales of digital cameras first exceed those of film cameras?
