## Rachel98 2 years ago Give the domain and range of the relation. Tell whether the relation is a function. How do you find the domain and range of a circle graph? For example, the one in the comments.

The domain would conventionally be defined as $D=\left\{ x \in \mathbb{R} : -3 \le x \le3 \right\}$ Does this help you to find the range?

So the range would be 2 ≤ Y ≤ - 2?

indeed yes
