A lake near to Arctic is covered by a 4 meters thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to melt at a constant rate. After 2 weeks, the sheet is only 1.6 meters thick. Let f(t) donate the ice sheet's thickness (measured in meters) as a function time t (measured in weeks). Write the function formula.
