Domain: ${-7, 5}$

Range: ${0, 3, 8}$

The domain is also known as the $x$ -values and the range is the $y$ -values.

Since we know that a coordinate is written in the form $(x, y)$ , all the $x$ -values are:
${5, -7, -7, 5}$

However, when we write a domain, we typically put the values from least to greatest and do not repeat numbers. Therefore, the domain is:
${-7, 5}$

All the $y$ -values are:
${0, 8, 3, 3}$

Again put them in least to greatest and do not repeat numbers:
${0, 3, 8}$

Hope this helps!
