Chapter 2: Q. 15 (page 68)

Determine whether each relation represents a function. For each function, state the domain and range.

Short Answer

Expert verified

The domain of the function is {Elvis,Colleen,Kaleigh,Marissa}and range is{Jan.8,Mar.15,Sept.17}.

Step by step solution

01

Step 1. Given Information

In the given question we have to determine whether each relation represents a function and for each function, we have to state the domain and range.

02

Step 2. The relation in Figure is a function because each element in the domain corresponds to exactly one element in the range.

The domain of the function is{Elvis,Colleen,Kaleigh,Marissa}

03

Step 3. The set of all images of the elements in the domain is called the range of the function.

The range of the function is {Jan.8,Mar.15,Sept.17}

It is okay for more than one element in the domain to correspond to the same element in the range.
