Is this a function
{(-7,-8),(-6,-8),(-4,-6),(-8,5),(-6 ,4)}
Then state the Domain and Range.

This is not a function

Domain: -7, -6, -4, -8

Range: -8, -6, 5, 4

Step-by-step explanation:

This is not a function because one x-values repeats, -8. The x-value is the first value in a relation. Relations are written as (x,y)

Domain is the x-values in a relation. When writing the domain, make sure not to include repeats. In this case, the domain is -7, -6, -4, -8.

Range is the y-values in a relation. Also, don't repeat when writing range. The range of this function is -8, -6, 5, 4
