Solve the problem.On January 8, ten students come down with the flu. Assume that each day, the number of students who come down with the flu doubles. So, for example, 20 students come down with the flu on January 9. Let f(t) represent the number of students who come down with the flu at t days after January 8.i) Find an equation for f.ii) Find f(7). What does your result mean in terms of the situation?
