Today

- Recap on Algebraic forms of a quadratic functions

- Recap on transformations of transformations. 

- Answers from Worksheet 2.2

Learning goals

- I know how to convert a quadratic function from the quadratic form to the vertex form by completing the square

- I know how to identify the vertex (“top”) from a quadratic function in the vertex form

Algebraic forms of a quadratic functions

Standard forms of a quadratic functions

y=ax​2​​+bx+c

Algebraic forms of a quadratic functions

The factorized form of a quadratic funtions is 

The vertex form of a quadratic function

Example: 

Example: 

Working Schema of writing in vertex form

From standart form to vertex form

y=x​2​​+2x−2

1. y=(x−1)​2​​−3
2. y=(x−1)​2​​+3
3. y=(x+1)​2​​−3
4. y=(x+2)​2​​−3

Recap on transformations of transformations. 

Worksheet 2.2

Graph transformations part 2

We can make this worksheet in the classroom. Because it is not so clear for students combinations of transformations.
