Domain And Range Of A Function Set Builder Notation

Set builder notation is very useful for defining domains.

Domain and range of a function set builder notation. I have been given the following relations to find the domain and range of using builder notation. As we will quickly see set builder notation is very easy to use and apply when finding the domain and range of a relation either as a set of ordered pairs or a mapping diagram. In the previous examples we used inequalities and lists to describe the domain of functions.

There are many different symbols used in set notation but only the most basic of structures will be provided here. If f x 2 x 5 the domain of f is x x is not equal to 5 more examples showing the set builder notation. We can also use inequalities or other statements that might define sets of values or data to describe the behavior of the variable in set builder notation for example latex left x 10 le x 30 right latex describes the behavior of latex x latex in set builder notation.

1 begingroup sorry about that the other names for it is math 8 or pre algebra. When using set notation we use inequality symbols to describe the domain and range as a set of values. 1 x 9.

The function must work for all values we give it so it is up to us to make sure we get the domain correct. Im not sure how to explain it anymore. The domains and ranges used in the discrete function examples were simplified versions of set notation.

The blue writing is what i have so far i am just beginning to learn the whole concept of set builder notation and i am running into a little confusion. But we are going to broaden our scope to determining both the domain and range of graphs where we will need a new perspective when finding elements for each set. I understand the x and y axis as well as the form it is written in.
