Every day, there are 5 times more likes on an internet video of a dog which is modeled by the function c(n) = (5)n − 1, where n is the number of days since the video posted. On the first day, there were 103 likes. What is the function that shows the number of likes each day?

  1. I think you may mean 5^(n-1)

    try y = 103 * 5^(n-1)

    when n = 1, y = 103 * 5^0 = 103
    when n = 2, y = 103*5^1 = 103*5
    when n = 3, y = 103*5^2 = 103*5*5 etc
