Chapter 2: Q16. (page 60)

Use the table of record high temperatures F鈭�for January and July.

Is this relation a function? Explain.

Short Answer

Expert verified

No, the given relation is not a function.

Step by step solution

01

– Definition of a function.

A relation is a function if each element of the domain is paired with exactly one element of the range and a relation is not a function if there exist an element in the domain paired with more than one element of the range.

02

– Given information.

The table of record high TemperaturesF鈭� for January and July.

Assume that the January temperatures are the domain.

03

– Check whether the relation is a function.

This relation is not a function because 88 in the domain is paired with 97 and 95 in the range.

Thus, therelation is not a function.
