Section 9. 3 Day 1 Transformations of Quadratic Functions Algebra 1

Learning Targets Define transformation, translation, dilation, and reflection Identify the parent graph of a quadratic function Graph a vertical and horizontal translation of the quadratic graph Describe how the leading coefficient of a quadratic graph changes the dilation of the parent graph Graph a reflection of a quadratic graph Identify the quadratic equation from a graph

Key Terms and Definitions Transformation: Changes the position or size of a figure Translation: A specific type of transformation that moves a figure up, down, left, or right.

Key Terms and Definitions Dilation: A specific type of transformation that makes the graph narrower or wider than the parent graph Reflection: Flips a figure across a line
