I REALLY need some help! Please help! (Algebra 2) **I always give a medal to the person with the best answer** Every day, there are 2 times more likes on an internet video of a bird which is modelled 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? A. c(n) = (2)122 − 1 B. c(n) = 122(2)n − 1 C. c(n) = (2)(122)(n − 1) D. c(n) = (122)n − 1

What is the meaning of "(2)n" or "(2)(122)" in this context ?

I have no idea. Nothing in this class makes any sense to me :l

I have been giving people this site and it's been really helpful to them, maybe you would like it to. http://www.wolframalpha.com/input/?i=%E2%88%92x2+%2B+5x+%2B+6+%3D+3x+%E2%88%92+2%3F

Just put in any equation or problem and it will break it down step by step.

Doesn't really help much. The question sounds simple enough but I'm intrigued by this notation I've never seen before in my life.

But, I'm not exactly sure how to set this equation up

@ganeshie8 Think you might be able to help with this Algebra 2 question?

Sorry about that, was afk. Well, starts with 122 likes after the first day so naturally for n=1 , c(n)=122. Then it says the number of likes doubles every day so for n=2 we have 244 likes, n=3 we have 488 likes and so forth which indicates an exponential growth. So the answer, outside the context of those notations I am not familiar with, should be something like c(n)=(2^(n-1))*122 in order to verify the context.

But again, I am not at all sure since I have never seen "(2)(122)" in my life.

Well, it's not any of the answer choices, so I don't know what to do ):
