Question

What is the domain and range of this and it is a function?

Answer 1

Answer:

Domain: [-8,inf)

Range: [-3,5]

Function: Yes

Step-by-step explanation:

First, this relation is a function because x's never repeat. The domain is every x-value that the graph covers, on this graph x's start at -8, which is included, and then continue forever. So the domain should be written as [-8,inf) because it is from least to greatest and the bracket shows -8 is included. The range is the y-values the graph covers. On this, the highest y is 5, and then the graph flattens at -3, both points are included. So the range must be [-3,5].
