Understanding Parent Functions and Graph Transformations

The video tutorial explains the concept of parent functions, focusing on the square root function. It covers how to graph transformations by applying horizontal and vertical shifts. The tutorial uses Desmos to demonstrate these transformations, providing a visual understanding of how equations change the graph's position.

What is a parent function?

• A function that has been transformed

• The original graph of a function

• A function with multiple variables

• A function that does not cross the origin

Which of the following is the parent function for a linear graph?

• y = x^2

• y = x^3

• y = x

• y = √x
