Transforming Parent Functions with Vertex Form

The video tutorial covers graph transformations, focusing on linear, absolute value, and quadratic functions. It explains how to plot functions using tables and points, introduces vertex form, and demonstrates transformations with examples. The tutorial emphasizes understanding transformations to simplify graphing and provides strategies for identifying changes in graphs.

How would you write the equation of a quadratic function that is shifted right 3 units, down 5 units, and stretched by a factor of 4?

• y = 4(x - 3)^2 + 5

• y = 4(x + 3)^2 + 5

• y = 4(x - 3)^2 - 5

• y = 4(x + 3)^2 - 5
