There are 512 players in a tennis tournament. In each round, half of the players are eliminated. Which function can be used to find the number of players remaining in the tournament at the end of x rounds?

Answer 1

The function that can be used to find the number of players remaining in the tournament at the end of x rounds is:

\[ f(x) = 512 \times \left(\frac{1}{2}\right)^x \]

where f(x) represents the number of players remaining after x rounds.

Answer 2

g(x) = 512 (1.50)^x
g(x) = 512 (0.50)^x
g(x) = 512 (1.05)^x
g(x) = 512 (0.05)^x

Answer 3

Among the options provided, the correct function that represents the number of players remaining in the tournament at the end of x rounds is:

\[ g(x) = 512 \times (0.50)^x \]
