How to find the domain and range of a function of a graph

The video tutorial explains how to determine the domain and range of a graph. The domain is the set of all possible X values for which the function is defined, while the range is the set of all possible Y values. The tutorial uses a continuous graph to illustrate these concepts, showing that the domain is from -4 to 4 and the range is from 0 to 4. It emphasizes using closed brackets to include boundary values and provides alternative notations for expressing domain and range.

What is the domain of a function?

• The set of all X values

• The set of all Y values

• The set of all Z values

• The set of all values greater than zero

In the given graph, what is the domain?

• From 0 to 8, inclusive

• From -4 to 4, inclusive

• From -4 to 0, inclusive

• From 0 to 4, inclusive

Which of the following is a correct way to express the domain?

• 0 ≤ X ≤ 4

• -4 ≤ X ≤ 4

• X > 4

• -4 < X < 4

What is the range of the graph discussed?

• From -4 to 0, inclusive

• From 0 to 4, inclusive

• From -4 to 4, inclusive

• From 0 to 8, inclusive

How should you associate domain and range with coordinates?

• Domain with Y and Range with X

• Domain with Z and Range with Y

• Domain with X and Range with Y

• Domain with Y and Range with Z
