The video tutorial explores the graph of y = √x, discussing its domain and how it can be transformed through vertical and horizontal shifts, as well as flipping over axes. The tutorial explains how adding constants outside or inside the radical affects the graph's position and orientation, and demonstrates these transformations with examples.

What is the domain of the function y = √x?

• x > 0

• x ≤ 0

• x ≥ 0

• x < 0

What is the value of y when x = 4 for the function y = √x?

• 3

• 4

• 2

• 1
