Blog Introduction

Hey! I'm using this blog as means to help improve my math skills. I'm really, really bad at math, but I really love blogging. Fandoms have taken over my life. I find I learn well by making things pretty and compiling notes, and so I'm hoping I can treat math like I would with a fandom. I don't know if this will help me finish the semester with my ideal grade, but we'll see.

functions

"for every x value there is one, and only one y value"

= for every input, there is one, and only one output

So for example, if you input 1 hour, you would only get one output of 50km. If you input 2 hours, your only output would be 100km, etc etc.

Domain vs range vs codomain

Domain: set of inputs accepted by the function ("what x can be")

Range: set of outputs from the given set of inputs

Codomain: ever output possible

Imagine you have a car driving. Each hour it drives 50 kilometers. It's been driving for four hours.

In this scenario, the domain would be each hour it drives. The codomain would be the 50 kilometers it can go every hour. This includes the hours that it hasn't driven yet. And the range is anywhere between 0 and 200.
