Domain and Range

Domain and Range To the best of your understanding, explain this picture. What is it representing?

Domain and Range These are representations of mappings (connections). The on the left is a simple relation, while the on the right is a function. Do you remember why?

Domain and Range These two differ in another important way. What type of thing is in the domain of each, and what type of thing is in the range?

Domain and Range The left is a mapping of a set of integers onto a set of integers. The right is a set of letters mapped onto, or connected to a set of integers.

Domain and Range This set of barcodes maps onto this set of prices. Is it important For this mapping to be a function? Why or Why not?

Domain and Range Is this mapping still a function? Why or why not? Why is this situation acceptable or not acceptable?

Domain and Range Is this mapping still a function? Why or why not? Why is this situation acceptable or not acceptable?

Domain and Range Our past definitions and understandings of Domain and Range, while correct, may be too narrow. This picture does not necessarily represent the Rx. R, or (x, y) mapping that we have previously used.

Domain and Range The graph of this Rx. R mapping has a restricted Domain. How would restricting a Domain affect the Range? How does it affect the Range in this example. Can you find the mapping rule?

Domain and Range These different representations all mean the same thing. “The number is greater than 5 and less than or equal to 8. ” When stating a numerical Domain or Range we will try to use the ( ), [ ), ( ], and [ ] symbols to express them.
