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\left(x\right)=512\left(1.50\right)^{x}
g\left(x\right)=512\left(0.50\right)^{x}
g\left(x\right)=512\left(1.05\right)^{x}
\ g\left(x\right)=512\left(0.05\right)^{x}

Answer 1

g(x) = 512(0.5)^x
