Exploring Linear Transformations in Algebra

The video tutorial covers the basics of linear functions, focusing on parent functions and their transformations. It explains how to graph linear functions using a calculator and delves into the concepts of horizontal and vertical translations. The tutorial provides examples and exercises to help students understand how these translations affect the graph of a function.

What is the parent linear function?

• f(x) = x^2

• f(x) = x

• f(x) = 2x

• f(x) = x + 1
