The domain of a function is the set of all inputs, or x values. The range is the set of all possible outputs, or y values. These might be discrete numbers that you'd list with commas, or a range of numbers that you'd need to describe using inequality or set notation. Here we focus on finding the domain and range from a graph where the domain represents possible side-to-side x values, and the range is up-and-down y values. Be wary of discontinuities like open holes or gaps in the function, and pay attention to endpoints versus ends with arrows.
