Learn how to determine the domain and range from a table and from a graph

The video tutorial explains the concepts of domain and range in mathematics, focusing on how they are represented in tables and graphs. It highlights the differences between finite tables and infinite graphs, emphasizing the importance of understanding that graphs consist of infinite points. The tutorial also discusses potential restrictions on domain and range, using examples to illustrate these concepts. The teacher addresses common student misunderstandings and stresses the need for attention to detail when analyzing graphs.

What is the definition of the domain in the context of a function?

How do you determine the domain from a table of values?

What challenges do students face when determining the domain and range from a graph?

Explain why a graph is considered to have infinite points.

What are the restrictions on the domain of a graph?

How do you identify the range of a function from its graph?

What is the lowest value that the graph can reach, and how does it affect the range?
