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

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

From the question, the information modeling the growth in the like of the video has been modeled by

c (n) = 2n-1

where n is the number of days

thus given that there were 122 likes on the first day, the function showing the number of like each day will be:

c (n) = 122 (2) ⁿ-1
