Every day, there are 2 times more likes on an internet video of a bird which is modeled by the function c(n) = (2)n − 1, where n is the number of days since the video posted. On the first day, there were 122 likes. What is the function that shows the number of likes each day?

c(n) = (2)122 − 1
c(n) = 122(2)n − 1
c(n) = (2)(122)(n − 1)
c(n) = (122)n − 1

psirockin2 · Answer

c(n) = 122(2)^(n − 1) I believe

why?

psirockin2 · Answer

Because it's modeled by c(n) = (2)n − 1 and the likes are doubling each day.
