In the realm of mathematics, there’s a captivating phenomenon known as exponential growth and decay. It’s like the mathematical equivalent of a snowball rolling down a hill, gaining momentum at an accelerated pace. Let’s dive into this thrilling concept and explore its significance in our everyday lives.

Types of Exponential Growth and Decay

There are two main types of exponential growth and decay: continuous and discrete. Continuous growth or decay unfolds smoothly over time, like the ticking of a clock. Discrete growth or decay, on the other hand, occurs in distinct steps or intervals, like a series of heartbeats.

Discrete Growth: The Stairway to Progress

Imagine a flight of stairs leading up to a magnificent castle. Each step represents a discrete interval of growth. With each step, you climb higher and higher towards your destination. Simarly, in discrete growth, the function increases or decreases by a fixed amount at regular intervals.

Examples of discrete growth include:

• The population of a city that grows by a certain number of people each year.
• The amount of money in a savings account that earns interest compounded periodically.
• The spread of a virus that infects a fixed number of individuals at specific intervals.

Understanding discrete growth is crucial in fields like population modeling, financial planning, and epidemiology. It empowers us to make informed decisions about complex systems that exhibit discrete growth or decay patterns.

Half-Life: The time it takes for the function to decrease to half its initial value.
