How to determine the domain and range from a function graph

The video tutorial explains the concepts of domain and range, comparing their representation in tables and graphs. It highlights the infinite nature of points in graphs and discusses domain restrictions. The tutorial also analyzes the range of a graph, emphasizing the differences between finite tables and infinite graphs.

What is the main difference between listing domain and range in a table versus a graph?

• Graphs and tables both list infinite values.

• Tables and graphs both list finite values.

• Graphs can list infinite values, tables cannot.

• Tables can list infinite values, graphs cannot.

Why can't we list every point in the domain of a graph?

• Because graphs have a limited number of points.

• Because graphs can have infinite points.

• Because tables are more accurate.

• Because graphs are not used for domain representation.

What is a characteristic of the domain of a graph that extends to infinity?

• It contains no points.

• It contains infinite points.

• It contains only negative values.

• It contains only positive values.

How do you determine the lowest Y value in the range of a graph?

• By listing all Y values.

• By identifying the lowest point the graph reaches.

• By finding the highest X value.

• By calculating the average of Y values.

What happens to the Y values as the graph extends upwards?

• They decrease.

• They disappear.

• They increase.

• They remain constant.
