Learn how to determine the domain of a radical function

The video tutorial explains how to visually determine if a graph represents a function using the vertical line test. It discusses the concept of domain and range, particularly focusing on functions involving square roots. The tutorial provides a step-by-step method to determine the domain of a function with a radical expression, emphasizing that the expression inside the square root must be non-negative.

What is the vertical line test and how is it used to determine if a graph represents a function?

Explain how to identify the domain of the function F of X = sqrt(X - 1).

What does it mean for a function to have an output for every input?

What values cannot be used as inputs for the function F of X = sqrt(X - 1) and why?

How do you solve for the domain of a function that includes a radical?
