STANDARD 12: EXPONENTIAL GROWTH AND DECAY
Many real world phenomena can be modeled by functions that describe how things grow or decay as time passes. Examples of such phenomena include the studies of populations, bacteria, the AIDS virus, radioactive substances, electricity, temperatures and credit payments, to mention a few.
Any quantity that grows or decays by a fixed percent at regular intervals is said to possess exponential growth or exponential decay.
The pattern is modeled by these functions:
