I’ll solve number 3.

You need to group the like terms. For example, -4n + 6n = 2n

8=2n

Now, we need to keep n by itself.
2n/2 = n

Whatever you do to one side, you need to do to the other.

8/2 = 4

So, in conclusion, n = 4.

I hope this helps for you to solve the rest!

Every day, there are 4 times more likes on an internet video of a horse which is modeled by the function c(n) = (4)n − 1, where

Answer:

f(n) = 100·4^(n-1)

Step-by-step explanation:

The given function c(n) is apparently the multiplier for n days. Its value is 1 for n=1, so we simply need to multiply c(n) by 100:

f(n) = 100·c(n) = 100·4^(n-1)
