What is the definition of range of a relation

The video tutorial explains the concepts of domain and range in mathematics, relating domain to input values and range to output values, often referred to as Y coordinates. It uses ordered pairs to illustrate the relationship between input and output. The tutorial further explores how these concepts apply to graphs, particularly piecewise graphs, and explains how to determine the range of Y values, which can extend to infinity. The explanation aims to clarify these fundamental concepts for students.

What is the domain in a set of ordered pairs?

• The difference between X and Y coordinates

• The sum of X and Y coordinates

• The X coordinates

• The Y coordinates

In a graph, what does the range represent?

• The lowest point on the graph

• All the X values

• All the Y values

• The highest point on the graph

How can the range of a graph be described?

• Both A and B

• From negative infinity to a specific value

• From a specific value to infinity

• Neither A nor B

What is the range of a graph that starts at 3 and goes up?

• From 3 to negative infinity

• From negative infinity to 3

• From 3 to infinity

• From 0 to 3

Which of the following best describes the range in terms of coordinates?

• Both X and Y coordinates

• Z coordinates

• Y coordinates

• X coordinates
