Answer:
32768
Step-by-step explanation:
Let x be the numer of months elapsed after you tube started and y represent the number of subscribers.
Obviously y(0) =8
After 1 month, y doubles and this continues for each month.
This can be written as
[tex]y(x) =8(2)^{x}[/tex]
where x= the numer of months elapsed after you tube started
Here domain cannot be negative
Domain =[0,infty)
b) In one year, number of subscribers
= [tex]y(12) =8*2^{12][/tex]
=32768
