### Introduction to Quadratics

## Friday, April 5th (A Day) or Monday, April 8th (B Day)

Today, you will be introduced to Quadratic Functions. During the lesson, you will complete the following tasks:

**Warm Up** - watch video to complete definitions of key terms used today

**Video Notes** - take notes from the video "Introduction to Quadratic Functions"

**Online calculator tutorial** - watch video that walks you through the steps to find the vertex of a quadratic function

**CW/HW** - complete the homework over the different parts of a quadratic function: vertex, axis of symmetry, domain and range

## Warm Up

## Video Notes

Watch the following video and fill out the notes titled "7.1 Video Notes - Introduction to Quadratic Functions." For the EOC Review, you may need to do some research on your own to answer those questions. They will **not** be covered in the video presentation.

*** The Random example in the video is **not** correct. I have provided a different example on your notes for you. Everything is already filled in except for the vertex and whether the vertex is a maximum or minimum. You may go ahead and answer the max or min question. You will need further instruction before you can correctly determine the vertex.***

## Online Calculator Tutorial

Watch the following video to learn how to use the calculator to find a **maximum** or **minimum** vertex on a parabola.

*** Please use this tutorial to determine the vertex for the "Random example" on the front page of your notes (orange paper). You may also use this tutorial to help you with the practice problems at the end of your notes as well.***
