Question

A recent trend in advertising is viral marketing. The goal is to convince viewers to share an amusing advertisement by e-mail or social networking. Imagine that the video is sent to 100 people on day 1. Each person agrees to send the video to 5 people the next day, and to request that each of those people send it to 5 people the day after they receive it. The number of viewers v ( n ) is an exponential function of the number n of days since the video was first shown.

Answer 1

Think of it as a branch. Everyone in a group of five will send it to five. Like a branch. It would be 25 for every person. So each person will send it to five people too. So my best answer would be 100(25) or 100(5) with the exponent of 5 would be my best guess.

Answer 2

Let a= Number of people.
Video sent on day 1: a=100
Then 100 people sent it to next 5 people on second day.
Which is b= 5
Exponential Equation for the given case:
V(n)= ab^n
Put values

`V(n)=100 * 5^n`

Answer:
`V(n)=100 * 5^n`
