The number of players of an online game triples each week. The function f (x) = 3^x represents the number of players in week x. When are there 81 players?

Week 4

Step-by-step explanation:

The function we have is

f (x) = 3ˣ

If there are 81 players, this gives us

81 = 3ˣ

81 = 9 (9) = 3 (3) (3) (3); this gives us

3 (3) (3) (3) = 3ˣ

This means x = 4

The equation to use here is 3^x = 81. You could start to try numbers, and you would realize that x = 4 weeks.
