In other words, the domain is all x-values or inputs of a function, and the range is all y-values or outputs of a function.

How to get the domain and range from the graph of a function

The domain is all x-values or inputs of a function and the range is all y-values or outputs of a function. When looking at a graph, the domain is all the values of the graph from left to right. The range is all the values of the graph from down to up.
