Chapter 8: Q23. (page 405)

Suppose a relation is represented as a set of ordered pairs and as a mapping diagram. Which representation more clearly shows whether or not the relation is a function? Explain.

Short Answer

Expert verified

Mapping diagram shows more clearly that a relation isa function.

Step by step solution

01

Step 1. Given Information.

Suppose a relation is represented as a set of ordered pairs and as a mapping diagram.

02

Step 2. Explanation.

Mapping diagram is a visual representation and ordered pair is a theoretical representation.

We know that visual representation is more effective than theoretical representation.

03

Step 3. Conclusion.

The mapping diagram shows more clearly that a relation is a function.
