A famous actor updates his fans about his life through a service that allows him to send out text-based posts over the internet. The number of his followers can be modeled by the
function f (d) = 4 (2^d),-4 Where f(d) is the number of followers and d is the number of days
since the actor opened his account. How many days after the actor opened his account did he
have 252 followers?
