Divide two functions and determine the domain

The video tutorial explains the concept of functions F of X and G of X, and how to evaluate them. It discusses the domain of these functions, particularly focusing on the inclusion and exclusion of certain values. An example problem is solved, demonstrating how to evaluate G of X over F of X for a specific value, highlighting the importance of understanding domain restrictions.

What is the expression for G(x) if F(x) is x^2?

• x^2 - 1

• x^2 + 1

• x - 1

• x + 1

Why is -1 not included in the domain of the function?

• Because it is not a real number

• Because it makes both numerator and denominator zero

• Because it makes the denominator zero

• Because it makes the numerator zero

What symbol is used to represent that -1 is not included in the domain?

• Angle bracket

• Bracket

• Parenthesis

• Curly brace

What is the result of evaluating G(x)/F(x) when x = 3?

• 1/3

• 9/4

• 3/9

• 4/9

What operation is performed to evaluate G(x)/F(x) for a specific value?

• Multiplication

• Subtraction

• Addition

• Substitution
