# Functions

### Topics

## Introduction to :

Some functions are less expressive than others. We're not trying to be judgey, here: it's true. For example, take the graph of a linear function. (We like *x *= 4; there's a lot of history there.) Draw your line on a coordinate plane, step back, and squint. It's so *linear*. Simple. Predictable.

Look, we're not saying it's boring, but...yeah. It kind of is.

In this section, we'll be taking a look at **quadratic** and **exponential** functions before banking a sharp left and exploring the wonderful world of **inequalities**. Trust us, things are about to get a lot more exciting around here.

At least in algebra terms, anyway.
