Question

-Every day, there are 4 times more likes on an internet video of a horse which is modelled by the function c(n) = (4)n − 1, where n is the number of days since the video posted. On the first day, there were 100 likes. What is the function that shows the number of likes each day?

c(n) = 100(4)n − 1

c(n) = (4)(100)(n − 1)

c(n) = (100)n − 1

c(n) = (4)100 − 1
