Annual sales (in millions of units) of pocket computers are expected to grow in accordance with the following function where t is measured in years, with t = 0 corresponding to 1997.
f(t) = 0.18t^2 + 0.16t + 2.64 (0<=t<=2)
How many pocket computers will be sold over the 2 year period between the beginning of 1997 and the end of 1998?
