Domain And Range Set And Interval 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.
Domain and range set and interval notation. Write the domain and range in set builder notation and interval notation. We can write the domain and range in interval notation which uses values within brackets to describe a set of numbers. Notation plays an important role in mathematics. What are the domain and range of the function.
Interval notation is a method used to write the domain and range of a function. Eq y 6x 2x 2 eq. When using set notation we use inequality symbols to describe the domain and range as a set of values. In interval notation there are five basic symbols to be familiar with.
The domains and ranges used in the discrete function examples were simplified versions of set notation. Open parentheses closed parentheses infinity imagine an 8 sideways negative infinity an 8 sideways with a negative sign in front of it and union a symbol similar to an elongated u. There are many different symbols used in set notation but only the most basic of structures will be provided here. Share your videos with friends family and the world.
In the previous examples we used inequalities and lists to describe the domain of functions.
