Write the exponential function for :

  Your heart rate reaches 58 bpm and then increases by 20% each minute.

•  $f\left(x\right)\ =\ 58\ \left(.20\right)^x$ 

•  $f\left(x\right)=\ 58\left(1.20\right)^x$ 

•  $f\left(x\right)\ =\ 20\left(.58\right)^x$ 

•  $f\left(x\right)=\ 58\left(.80\right)^x$ 

Write the exponential function for :


 An account with $25,000 decreases in value 9% each year.

•  $f\left(x\right)\ =\ 25,000\left(.90\right)^x$ 

•  $f\left(x\right)=25,\ 000\left(0.09\right)^x$ 

•  $f\left(x\right)\ =\ 25,000\left(.91\right)^x$ 

•  $f\left(x\right)=\ 25,000\left(1.09\right)^x$
