Growth

Decay

Use the following exponential growth/decay models to choose a function, f(t), and evaluate the specified amounts described in problems 5-8.

Exponential Growth: $f (t) = a {(1 + r)}^{t}$ Exponential Decay: $f (t) = a {(1 - r)}^{t}$

P. J. is trying to help the environment by recycling more material and reduce his waste. The first month, P. J. recycles 5 pounds of re-usable materials, and increases that amount by an average of 22% each month. Write the equation for the function, f(t), where t is the number of months that P. J. recycles.

$f (t) = 5 {(1.19)}^{t}$

$f (t) = 5 {(1.20)}^{t}$

$f (t) = 5 {(1.21)}^{t}$

$f (t) = 5 {(1.22)}^{t}$
