Jesse sent an email to 4 people for a school project. In her email, she requested that each person copy and send the same email to 4 additional people.
If everyone continues to send the email as requested, which equation could be
used to determine the number of emails, y, that will be sent for a given round, x?
M. y = x^4
P. y = 4^x
R. y = 4x
a. y= 4/x

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
