Exponential Growth and Decay

Front

What is Exponential Growth?

Back

Exponential Growth occurs when a quantity increases by a consistent percentage over a period of time, resulting in a rapid increase. Example: Population growth where the number doubles at regular intervals.

What is Exponential Decay?

Back

Exponential Decay occurs when a quantity decreases by a consistent percentage over a period of time, leading to a rapid decrease. Example: Radioactive decay of a substance.

What is Linear Growth?

Back

Linear Growth occurs when a quantity increases by a constant amount over equal intervals of time. Example: A person saving a fixed amount of money each month.

What is the difference between Linear and Exponential functions?

Back

Linear functions increase or decrease at a constant rate, while Exponential functions increase or decrease at a rate proportional to their current value.

Front

What is the formula for Exponential Growth?

Back

The formula is: P(t) = P0 * e^(rt), where P0 is the initial amount, r is the growth rate, and t is time.

What is the formula for Exponential Decay?

Back

The formula is: P(t) = P0 * e^(-rt), where P0 is the initial amount, r is the decay rate, and t is time.

What does the 'e' represent in Exponential functions?

Back

The 'e' is a mathematical constant approximately equal to 2.71828, which is the base of natural logarithms.
