Q:

Create a mapping diagram of the relation. Define the domain and range. Tell whether the relation is a function. For both.

Accepted Solution

A:
ANSWERFor the first relation the ordered pairs are:(-2,-5),(-2,3),(1,-1),(2,3),(6,2)The domain refers to set of x-values of the relation.Domain: {-2,1,2,6}Range {-5,-1,2,3}Range refers to the set of all y-values of the relation.This relation is not a function because -2 alone has two different y-coordinates which are -5 and 3.For the second relation, the ordered pairs are: (-5,-4), (-3,-2), (-2,1),(0,2),(2,1),(3,0)Domain: {-5,-3,-2,1,0,2,3}Range:{-4,-2,0,1,2}This relation is a function because no x-value maps on to more than one y-value.For a mapping diagram, the set of all the x-coordinates form the domain and the corresponding y-coordinates are in the RangeSee attachment for the mapping diagram s.
