Question

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

Answer 1

option B

Explanation:

Answer 2

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
