Exponential Growth or Decay Solving

This is an example of:

• Linear Growth

• Linear Decay

• Exponential Growth

• Exponential Decay

Classify the model as Exponential GROWTH or DECAY.
A=10(1.01)³

• Growth

• Decay

Which of the following equations shows an initial value of 21 and is exponential growth?

• y=21(0.85)xy=21\left(0.85\right)^xy=21(0.85)x

• y=21(1.13)xy=21\left(1.13\right)^xy=21(1.13)x

• y=15(1.21)xy=15\left(1.21\right)^xy=15(1.21)x

• y=100(0.21)xy=100\left(0.21\right)^xy=100(0.21)x

Would the following be modeled by exponential growth or exponential decay?

• exponential growth
