Question

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?

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

Answer 1

g(x) = 512(0.50)^x

This function represents the number of players remaining in the tournament at the end of x rounds, where half of the players are eliminated each round.
