The expenditure of a company for the period 2004 to 2012 can be given by the function y(t) = t^3 - 2t^2 -16t + 50 , where y is the expenditure (in thousands of dollars) and t is the number of years elapsed since 2004. During which period was the expenditure lower than $18,000 in each year? (Hint: 2004 translates to t = 0.)
