Answer:
P.y =
Step-by-step explanation:
From the given question, since Jesse sends the email to 4 people and the 4 people rebroadcast it to another 4 persons each. And this process continues for a required or given round x, then this is an example of an exponential function.
Thus, the number of emails sent for a given round can be expressed as;
y =
Therefore, the appropriate answer is y = .
So that for four rounds (x = 4), the number of emails sent can be determined as;
y =
=
y = 256
