Chapter 3 - Section 3.2 - Introduction to Functions - Exercise Set: 3

Answer

Domain: {-7, -2, 6}, Range: {-8, -3, 4}, No

Work Step by Step

The domain is the set of all first components of the ordered pairs, or {-7, -2, 6}. The range is the set of all second components of the ordered pairs, or {-8, -3, 4}. This relation is not a function because x=-2 corresponds to more than one component in the range.
