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.
