## Algebra 1: Common Core (15th Edition)

You have g(x)=14($2^{x}$).The growth factor is 2 because it is the number that allows x to grow as x changes. To find the initial amount plug in 0 for x: g(x)=14($2^{x}$) g(0)=14($2^{0}$) g(0)=14(1) g(0)=14 The initial amount is 14 and the growth factor is 2.
