Question

How do I find the domain n range of this graph​

Answer 1

Domain = {-3, 2}

Range = All real numbers

We can represent the range in interval notation as $(-\infty, \infty)$ which is basically saying $-\infty < y < \infty$. The range is all real numbers due to the arrows meaning the graph extends up and down forever. So any y value is possible.

Notice with the domain we only have 2 valid x values -3 and 2. No other x values are allowed. Normally we use an interval of some kind to set up the domain, but we only have a set of values instead. The curly braces indicate "set".
