Exploring Domain and Range in Functions

The video tutorial explains how to determine the domain and range of a relation by graphing points. It starts with plotting points on a graph, then identifies the domain as the set of x-values and the range as the set of y-values. The tutorial uses a specific notation to represent these sets and emphasizes that the domain and range include only the values present in the relation.

What is the first step in determining the domain and range of a relation?

• Writing the domain and range

• Identifying the points

• Graphing the relation

• Labeling the axes

Which point is plotted first in the graph?

• (3, 5)

• (-2, 5)

• (0, 6)

• (-2, 4)
