Exponential Growth and Decay Formulas

How is the exponential growth formula different from the exponential decay formula?

• They are not different.

• Exponential Growth requires you to multiply. Exponential Decay requires you to divide.

• Exponential Growth requires you to subtract your rate of increase. Exponential Decay requires you to add your rate of decay.

• Exponential Growth requires you to add your rate of increase. Exponential Decay requires you to subtract your rate of decay.
