Two members of a band want to get word out about their next gig. Jack's plan is that he can pass out 100 fliers a day. Meg has a different strategy. She wants to tell each of her friends about the performance on the first day, and ask each of her 10 friends to each tell a friend on the second day, and then everyone who has heard about the concert would tell a friend on the third day, and so on. Meg's idea can be modeled with the function M(t)=10(2)^2-1, where t is the number of days. What kind of function is Meg's idea? What about Jack's?
