How to identify the domain from the quotient of two functions

The video tutorial explains how to interpret and simplify the notation G of X / F of X, focusing on the functions G of X = sqrt(X) - 1 and F of X = 2X. It discusses the simplification process and the use of the distributive property. The tutorial then delves into domain restrictions, highlighting the importance of ensuring the denominator is not zero and the radicand is non-negative. Finally, it concludes with an analysis of domain constraints, determining that the domain is X > 0.

What is the significance of the radicand in the context of the square root function?

How do the constraints on X affect the domain of the function?
