the number of subscribers to a streaming video service doubles each week. The function f(x)=2^x represents the number of subscribers in a week x. when are there 64 subscribers?
For this case we have the following function: f (x) = 2 ^ x For f (x) = 64 we have: 64 = 2 ^ x Clearing the value of x we have: log2 (2 ^ x) = log2 (64) x = log2 (64) x = 6 Answer: there are 64 subscribers in: A. week 6
