How to determine the domain from quotient of two functions

The video tutorial explains the concept of functions, specifically focusing on F of X and G of X. It discusses how to identify the domain of these functions, emphasizing the restrictions when dealing with radicals and rationals. The tutorial highlights the importance of not having zero in the denominator and explains the use of brackets and parentheses to denote domain inclusion or exclusion.

What is the function F of X in the given example?

• 1/X

• Square root of X

• X^2 + 1

• X + 1

Why can't the square root of a negative number be taken?

• It results in an undefined value

• It results in zero

• It results in a complex number

• It results in a positive number

What is the significance of using parentheses in domain notation?

• It indicates the value is the only one in the domain

• It indicates the value is included in the domain

• It indicates the value is excluded from the domain

• It indicates the value is optional in the domain

What happens if zero is in the denominator of a function?

• The function becomes undefined

• The function equals zero

• The function equals infinity

• The function remains unchanged

How is the inclusion of zero in the domain represented?

• With a parenthesis

• With a curly brace

• With a bracket

• With a square
