Exploring Transformations of Parent Functions

This video tutorial covers chapter one, section five on parent functions and transformations. It begins with an introduction to basic parent functions such as linear, absolute value, quadratic, and cubic functions. The tutorial then explains transformations, including horizontal and vertical shifts, stretches, and shrinks. Graphing examples are provided to illustrate these transformations, with a focus on square root and cubic functions. Advanced graphing techniques are discussed, including the use of Desmos for visualizing transformations. The video concludes with a reminder to practice graphing and seek additional help if needed.

What is the shape of the graph for a linear function?

• A horizontal line
