Determine the domain and range from a set of values

The video tutorial covers how to find the domain and range from a set of ordered pairs. The teacher explains the concept of ordered pairs, their representation on an X&Y axis, and how to extract the domain and range. The domain consists of all X values, while the range consists of all Y values. An example problem is provided to illustrate the process.

What is the primary purpose of ordered pairs in mathematics?

• To find the difference between X and Y values

• To calculate the sum of X and Y values

• To show a relationship between X and Y values

• To determine the average of X and Y values

How do you find the domain of a set of ordered pairs?

• By identifying all the Y values

• By calculating the average of X values

• By identifying all the X values

• By subtracting Y values from X values

Which of the following is NOT a step in finding the domain?

• Identifying all X values

• Listing X values as the domain

• Rewriting points as X, Y pairs

• Calculating the sum of X values

What is the range of a set of ordered pairs?

• The set of all Y values

• The difference between X and Y values

• The set of all X values

• The sum of X and Y values

Which values are included in the range of ordered pairs?

• Only negative Y values

• All Y values

• All X values

• Only positive Y values
