Linear functions are common in mathematics and physics. They can be used to model many different processes that happen in the world around us, such as population growth or radioactive decay.

In this blog post, we will explore some linear function examples and learn more about their properties. The term linear function is a bit unusual because it does not correspond to the graph of any real-world situation.

In math, these functions are just ways to mathematically describe how one quantity changes with another while following specific rules. But that doesn’t mean they’re useless. Linear functions can be used for modeling many different processes in all sorts of fields from physics and chemistry to economics, anthropology, sociology and more.

We’ll start by looking at some examples where we see people using linear models in their work or research. A biologist might use a model like this when trying to figure out what happens if you change an animal’s diet (more on population growth below). Scientists studying radioactive decay often use graphs with lines sloping upwards.
