## Reflection: Complex Tasks Graphing Quadratic Functions in Vertex Form f(x)=a(x-h)^2 + k. - Section 1: Warm Up

Some of the difficulties that students have with Vertex Form depends on the form that they start with.  If students are given the Quadratic Function in Vertex Form, most students seem to develop an understanding for identifying the Vertex.

However, if the students are given the Quadratic Function in Standard Form, students may need to explore a few different ways to look at the problem.  One of the ways being completing the square to change from Standard Form to Vertex Form.  The other way may be easier for students to understand.  It is by finding the Vertex (h, k) by using the formula h=-b/2a and then finding k=f(h).

I demonstrate in the video below.

# Graphing Quadratic Functions in Vertex Form f(x)=a(x-h)^2 + k.

Lesson 3 of 10

## Big Idea: The Parent Function is the focus of this lesson to identify transformations of every point on the graph by identifying the transformation of the Vertex.
