Answer:
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
