Every day, there are 3 times more likes on an internet video of a cat which is modelled by the function c(n) = (3)n − 1, where n is the number of days since the video posted. On the first day, there were 143 likes. What is the function that shows the number of likes each day?

A) c(n) = (3)^(143)(n − 1)

B) c(n) = (143)^n − 1

C) c(n) = (3)^143 − 1

D) c(n) = 143(3)^n − 1

anonymous · Answer

day one = 143
so if i put x for 143 and i want to find out how much it gains based off of c(n) = 3n - 1
then c(n)=143 (3^n)-1
so D
