find the domain and range of the relation. use interval notation where appropriate. express numbers as…

Explanation:

Step1: Identify domain concept

The domain is the set of all x - values. Looking at the graph, the relation exists for all real x - values from negative infinity to positive infinity.

Step2: Write domain in interval notation

The domain in interval notation is $(-\infty,\infty)$.

Step3: Identify range concept

The range is the set of all y - values. From the graph, the relation exists for all real y - values from negative infinity to positive infinity.

Step4: Write range in interval notation

The range in interval notation is $(-\infty,\infty)$.

Answer:

Domain: $(-\infty,\infty)$ Range: $(-\infty,\infty)$
