## Lesson One - Factoring
### There are 4 types of factoring
* Simple Trinomial (adds to multiplies to)

## Lesson Two - Familiar Functions
A **relation** is: a relationship between two or more variables
A **function** is: a relation where each x value only has one y value
A relation is a function if it passes the vertical line test
## Lesson Three - Transformations |
### y= af(b(x-c)) + d
A: if -ve reflect of the x axis, vertical stretch by a factor of a (a > 1), vertical compression by 1/a (0
