Initial Amount: 14 Growth Factor: 2

Work Step by Step

The initial amount can be found by plugging in 0 for x: g(x) = (14)(2$^{x}$) g(0) = (14)(2$^{0}$) g(0) = (14)(1) g(0) = 14 The growth factor is 2 because this is the number attached to x. In other words, this is the growth factor because this is the number that allows x to grow as x changes.
