What is domain? What is range? How do you get from one to the other?

The domain is the set of all possible x-values which will make the function "work", and will output real y-values. (Minimun x value to maximum x value)

The range of a function is the spread of possible y-values (minimum y-value to maximum y-value)

Step-by-step explanation:

When trying to find the domain and range from a graph, the domain is found by looking at the graph from left to right. The range is found by looking at the graph from top to bottom.
