F(n) = 4n+ 3
g(n)= 4n-4
Find (f • g)(n)

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

8121 because

130,000 divided by 16 is 8121

2.83941151 would be the answer you're looking for! : )
