She had 8 subscribers at the beginning of the month. one month later, her number of subscribers doubled and continued to double each month. create a function to model the growth in the number of subscribers to the singer's channel since the month it had 8 subscribers. what is a reasonable domain in this situation?

Step-by-step explanation:

She had 8 subscribers at the beginning of the month. One month later, her number of subscribers doubled and continued to double each month

when month =0  the subscribers = 8    (0,8)

month =1 , subscribers = 16            (1,16)

month = 2, subscribers = 32  and so on         (2,32)

Subscribers are doubled every month

For exponential growth we use formula y=ab^x

where 'a' is the initial value. given initial value is 8 so a=8

To frame the function , we plug in (1,16) a=8 and solve for b

divide by 8 on both sides

b^1 = 2  so b= 2

Exponential function becomes (a=8,  b= 2)

She had 8 subscribers at the beginning of the month

So when month x=0  then the number of subscribers = 8

Domain x starts from 0 month and it goes on increasing

Domain x be the number of months.

the answer is 96 degrees

you have to realize that a line equals 180 degrees
