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)

What should be done before plotting the points on the graph?

• Write the equation

• Determine the range

• Determine the domain

• Label the axes

Which of the following points is not part of the given relation?

• (-2, 5)

• (-2, 4)

• (0, 6)

• (3, 5)

What is the domain of the given relation?

• {-5, 0, 3}

• {-2, 3, 0, -2}

• {4, 5, 6}

• {-2, 0, 3}

How is the domain represented in the video?

• Using angle brackets

• Using parentheses

• Using curly brackets

• Using square brackets

What does the domain tell us about the values of x?

• X can take any value

• X is always positive

• X is limited to specific values

• X is always negative

What is the range of the given relation?

• {-2, 0, 3}

• {-5, 0, 3}

• {4, 5, 6}

• {-2, 3, 0, -2}

How is the range represented in the video?

• Using parentheses

• Using curly brackets

• Using square brackets

• Using angle brackets

What does the range tell us about the values of y?

• Y is always negative

• Y is always positive

• Y is limited to specific values

• Y can take any value
